The secret documents do not reveal the precise targets of so much espionage by the NSA — and possibly its Canadian partner — during the Toronto summit. But both the U.S. and Canadian intelligence agencies have been implicated with their British counterpart in hacking the phone calls and emails of foreign politicians and diplomats attending the G20 summit in London in 2009 — a scant few months before the Toronto gathering of the same world leaders.

The spying at the Toronto summit in 2010 fits a pattern of economic and political espionage by the powerful U.S. intelligence agency and its partners such as Canada. That espionage was conducted to secure meeting sites and protect leaders against terrorist threats posed by al-Qaeda but also to forward the policy goals of the United States and Canada. The G20 summit in Toronto had a lot on its agenda that would have been of acute interest to the NSA and Canada.

The world was still struggling to climb out of the great recession of 2008. Leaders were debating a wide array of possible measures including a global tax on banks, an idea strongly opposed by both the U.S. and Canadian governments. That notion was eventually scotched. The secret NSA documents list all the main agenda items for the G20 in Toronto — international development, banking reform, countering trade protectionism, and so on — with the U.S. snooping agency promising to support "U.S. policy goals." Whatever the intelligence goals of the NSA during the Toronto summit, international security experts question whether the NSA spying operation at the G20 in Toronto was even legal.

"If CSEC tasked NSA to conduct spying activities on Canadians within Canada that CSEC itself was not authorized to take, then I am comfortable saying that would be an unlawful undertaking by CSEC," says Craig Forcese, an expert in national security at University of Ottawa's faculty of law. By law, CSEC cannot target anyone in Canada without a warrant, including world leaders and foreign diplomats at a G20 summit. But, the Canadian eavesdropping agency is also prohibited by international agreement from getting the NSA to do the spying or anything that would be illegal for CSEC.

The NSA warns the more likely security threat would come from "issue-based extremists" conducting acts of vandalism. They got that right. Protest marches by about 10,000 turned the Toronto G20 into an historic melee of arrests by more than 20,000 police in what would become one of the largest and most expensive security operations in Canadian history. By the time the tear gas had cleared and the investigations were complete, law enforcement agencies stood accused of mass-violations of civil rights. Add to that dubious legacy illegal spying by an American intelligence agency with the blessing of the Canadian government.

Yossi Cohen was appointed head of the Mossad a year ago, after a government vetting committee accepted that he had no personal ties to Netanyahu. But Cohen forgot to mention that he is extremely close to Netanyahu’s high-flying friends – connections that are now under investigation. Milchan set up a global security firm in 2008 called Blue Sky International, stuffed with Israeli security veterans. Packer soon became a partner. They developed close ties to Cohen, first while he was a senior official at the Mossad and later when he headed Israel’s national security council. Before Cohen was appointed head of Mossad in December 2015, the pair had hoped to recruit him to their cyber-security operations. Cohen received several gifts from Packer, in violation of Israeli government rules, including a stay at one of his luxury hotels. A source speaking to Haaretz said Blue Sky had “more than [a] direct line” to Netanyahu. They “would pull him out from anywhere, at any time, on any occasion.” According to Haaretz’s military analyst, Amir Oren, the new disclosures raise serious questions about whether Milchan and Packer twisted Netanyahu’s arm to parachute Cohen into the post over the favored candidate. In return, Packer may have been hoping that Cohen would authorise exceptional Israeli residency for him, classifying him as a security asset.

From Hollywood to Mossad Cases 1000 and 2000 share at least one figure in common. Milchan gave Netanyahu extravagant gifts over many years, but he is also reported to have acted as go-between, bringing arch-enemies Netanyahu and Mozes together. Milchan has his own financial stake in the media, in his case a holding in the Channel 10 TV station. In addition, Milchan introduced Netanyahu to sympathetic businessmen, including his friend Packer, to discuss taking the ailing Yedioth media group off Mozes’ hands. Only last October he arranged for media mogul Rupert Murdoch’s son, Lachlan, to fly to Israel for one night for a secret meeting with Netanyahu. Milchan is undoubtedly at the centre of the shadowy world of power and finance that corrupts public life in Israel. Not only is Milchan a highly influential Hollywood figure, having produced more than 100 films, but he has admitted that he is a former Mossad agent. He used his Hollywood connections to help make arms deals and secure parts for Israel’s nuclear weapons program. One can only wonder whether Milchan was not effectively set up in his Hollywood career as a cover for his Mossad activities. But Milchan, it seems, is still wielding influence in Israel’s twilight world of security.

eyond this, one one can only speculate about how Cohen’s indebtedness to Milchan, Packer and Netanyahu might have influenced his decisions as head of the Mossad. It was only a few years ago that the former Mossad chief, Meir Dagan, was reported to have wrestled furiously with Netanyahu to stop him launching a military strike on Iran. Prosecution drags feet It is unclear for the time being whether the revelations are drawing to a close or will lead deeper into Israel’s twin netherworlds of financial corruption and security. But what has emerged so far should be enough to finish off Netanyahu as prime minister. Whether it does so may depend on the extent of Israel’s compromised legal system. Attorney general Avichai Mendelblit was appointed by Netanyahu and is a political ally. He appears to have been dragging his feet as much as possible to slow down the police investigation, if not sabotage it. But the weight of evidence is looking like it may prove too overwhelming. As political analyst Yossi Verter observed: “There’s no way that a police commissioner … appointed [by Netanyahu] and a cautious attorney general, who in the past was part of his close circle and one of his loyalists, would be putting him through the seven circles of hell if they weren’t convinced that there’s a solid basis for indictment and conviction.” The next question for Netanyahu is whether he will step down if indicted. He should, if Olmert’s example is followed. But his officials are citing a 1993 high court ruling that allows a cabinet minister under indictment to remain in office. Certainly if Netanyahu chooses to stay on, his decision would be appealed to the court again. However, the judges may be reluctant to oust a sitting prime minister. The court of public opinion is likely to be decisive in that regard. A recent poll shows few Israelis believe Netanyahu is innocent of the allegations. Some 54 per cent think he broke the law, while only 28 believe him. Opinion, however, is split evenly on whether he should resign.

If past experience is any measure, Netanyahu will try to turn public opinion his way by increasing friction with the Palestinians and exploiting the international arena, especially his relations with the Trump administration. He may be expected to encourage Trump at the very least to posture more stridently against Iran. Nonetheless, most observers assume Netanyahu is doomed – it is simply a matter of when. The odds are on an indictment in late spring, followed by elections in the fall, say Israeli analysts. At this stage, none of his political rivals wants to be seen stabbing Netanyahu in the back. Most are keeping quiet. But behind the scenes, political leaders are hurrying to forge new alliances and extract political concessions while Netanyahu is wounded.

Who might succeed Netanyahu? Yair Lapid, of the centre-right Yesh Atid, is heading the polls, but that may in part reflect the disarray in Netanyahu’s Likud party. In a sign of where the deeper currents in Israeli society are leading, a Maariv poll last week showed that settler leader Naftali Bennett would win an election if he were to head the Likud. Netanyahu now needs the help of all the powerful friends he can muster. His biggest ally, U.S. casino magnate Sheldon Adelson, may not be among them. After the revelations that Netanyahu was conspiring against him with Mozes, Adelson has cut back on Israel Hayom’s circulation and is reported to be offering less favorable coverage of the Netanyahus. That could prove the final straw, sealing Netanyahu’s fate.

As the gap has grown between Washington’s global reach and its shrinking mailed fist, as it struggles to maintain 40% of world armaments (the 2012 figure) with only 23% of global gross economic output, the U.S. will need to find new ways to exercise its power far more economically. As the Cold War took off, a heavy-metal U.S. military -- with 500 bases worldwide circa 1950 -- was sustainable because the country controlled some 50% of the global gross product. But as its share of world output falls -- to an estimated 17% by 2016 -- and its social welfare costs climb relentlessly from 4% of gross domestic product in 2010 to a projected 18% by 2050, cost-cutting becomes imperative if Washington is to survive as anything like the planet’s “sole superpower.” Compared to the $3 trillion cost of the U.S. invasion and occupation of Iraq, the NSA’s 2012 budget of just $11 billion for worldwide surveillance and cyberwarfare looks like cost saving the Pentagon can ill-afford to forego. Yet this seeming “bargain” comes at what turns out to be an almost incalculable cost. The sheer scale of such surveillance leaves it open to countless points of penetration, whether by a handful of anti-war activists breaking into an FBI field office in Media, Pennsylvania, back in 1971 or Edward Snowden downloading NSA documents at a Hawaiian outpost in 2012.

In October 2001, not satisfied with the sweeping and extraordinary powers of the newly passed Patriot Act, President Bush ordered the National Security Agency to commence covert monitoring of private communications through the nation's telephone companies without the requisite FISA warrants. Somewhat later, the agency began sweeping the Internet for emails, financial data, and voice messaging on the tenuous theory that such “metadata” was “not constitutionally protected.” In effect, by penetrating the Internet for text and the parallel Public Switched Telephone Network (PSTN) for voice, the NSA had gained access to much of the world’s telecommunications. By the end of Bush’s term in 2008, Congress had enacted laws that not only retrospectively legalized these illegal programs, but also prepared the way for NSA surveillance to grow unchecked. Rather than restrain the agency, President Obama oversaw the expansion of its operations in ways remarkable for both the sheer scale of the billions of messages collected globally and for the selective monitoring of world leaders.

By 2012, the centralization via digitization of all voice, video, textual, and financial communications into a worldwide network of fiber optic cables allowed the NSA to monitor the globe by penetrating just 190 data hubs -- an extraordinary economy of force for both political surveillance and cyberwarfare.

With a few hundred cable probes and computerized decryption, the NSA can now capture the kind of gritty details of private life that J. Edgar Hoover so treasured and provide the sort of comprehensive coverage of populations once epitomized by secret police like East Germany’s Stasi. And yet, such comparisons only go so far. After all, once FBI agents had tapped thousands of phones, stenographers had typed up countless transcripts, and clerks had stored this salacious paper harvest in floor-to-ceiling filing cabinets, J. Edgar Hoover still only knew about the inner-workings of the elite in one city: Washington, D.C.  To gain the same intimate detail for an entire country, the Stasi had to employ one police informer for every six East Germans -- an unsustainable allocation of human resources. By contrast, the marriage of the NSA’s technology to the Internet’s data hubs now allows the agency’s 37,000 employees a similarly close coverage of the entire globe with just one operative for every 200,000 people on the planet

Through the expenditure of $250 million annually under its Sigint Enabling Project, the NSA has stealthily penetrated all encryption designed to protect privacy. “In the future, superpowers will be made or broken based on the strength of their cryptanalytic programs,” reads a 2007 NSA document. “It is the price of admission for the U.S. to maintain unrestricted access to and use of cyberspace.” By collecting knowledge -- routine, intimate, or scandalous -- about foreign leaders, imperial proconsuls from ancient Rome to modern America have gained both the intelligence and aura of authority necessary for dominion over alien societies. The importance, and challenge, of controlling these local elites cannot be overstated. During its pacification of the Philippines after 1898, for instance, the U.S. colonial regime subdued contentious Filipino leaders via pervasive policing that swept up both political intelligence and personal scandal. And that, of course, was just what J. Edgar Hoover was doing in Washington during the 1950s and 1960s.

Indeed, the mighty British Empire, like all empires, was a global tapestry woven out of political ties to local leaders or “subordinate elites” -- from Malay sultans and Indian maharajas to Gulf sheiks and West African tribal chiefs. As historian Ronald Robinson once observed, the British Empire spread around the globe for two centuries through the collaboration of these local leaders and then unraveled, in just two decades, when that collaboration turned to “non-cooperation.” After rapid decolonization during the 1960s transformed half-a-dozen European empires into 100 new nations, their national leaders soon found themselves the subordinate elites of a spreading American global imperium. Washington suddenly needed the sort of private information that could keep such figures in line. Surveillance of foreign leaders provides world powers -- Britain then, America now -- with critical information for the exercise of global hegemony. Such spying gave special penetrating power to the imperial gaze, to that sense of superiority necessary for dominion over others.  It also provided operational information on dissidents who might need to be countered with covert action or military force; political and economic intelligence so useful for getting the jump on allies in negotiations of all sorts; and, perhaps most important of all, scurrilous information about the derelictions of leaders useful in coercing their compliance.

In late 2013, the New York Times reported that, when it came to spying on global elites, there were “more than 1,000 targets of American and British surveillance in recent years,” reaching down to mid-level political actors in the international arena. Revelations from Edward Snowden’s cache of leaked documents indicate that the NSA has monitored leaders in some 35 nations worldwide -- including Brazilian president Dilma Rousseff, Mexican presidents Felipe Calderón and Enrique Peña Nieto, German Chancellor Angela Merkel, and Indonesia’s president Susilo Bambang Yudhoyono.  Count in as well, among so many other operations, the monitoring of “French diplomatic interests” during the June 2010 U.N. vote on Iran sanctions and “widespread surveillance” of world leaders during the Group 20 summit meeting at Ottawa in June 2010. Apparently, only members of the historic “Five Eyes” signals-intelligence alliance (Australia, Canada, New Zealand, and Great Britain) remain exempt -- at least theoretically -- from NSA surveillance. Such secret intelligence about allies can obviously give Washington a significant diplomatic advantage. During U.N. wrangling over the U.S. invasion of Iraq in 2002-2003, for example, the NSA intercepted Secretary-General Kofi Anan’s conversations and monitored the “Middle Six” -- Third World nations on the Security Council -- offering what were, in essence, well-timed bribes to win votes. The NSA’s deputy chief for regional targets sent a memo to the agency’s Five Eyes allies asking “for insights as to how membership is reacting to on-going debate regarding Iraq, plans to vote on any related resolutions [..., and] the whole gamut of information that could give U.S. policymakers an edge in obtaining results favorable to U.S. goals.”

Indicating Washington’s need for incriminating information in bilateral negotiations, the State Department pressed its Bahrain embassy in 2009 for details, damaging in an Islamic society, on the crown princes, asking: “Is there any derogatory information on either prince? Does either prince drink alcohol? Does either one use drugs?” Indeed, in October 2012, an NSA official identified as “DIRNSA,” or Director General Keith Alexander, proposed the following for countering Muslim radicals: “[Their] vulnerabilities, if exposed, would likely call into question a radicalizer’s devotion to the jihadist cause, leading to the degradation or loss of his authority.” The agency suggested that such vulnerabilities could include “viewing sexually explicit material online” or “using a portion of the donations they are receiving… to defray personal expenses.” The NSA document identified one potential target as a “respected academic” whose “vulnerabilities” are “online promiscuity.”

Just as the Internet has centralized communications, so it has moved most commercial sex into cyberspace. With an estimated 25 million salacious sites worldwide and a combined 10.6 billion page views per month in 2013 at the five top sex sites, online pornography has become a global business; by 2006, in fact, it generated $97 billion in revenue. With countless Internet viewers visiting porn sites and almost nobody admitting it, the NSA has easy access to the embarrassing habits of targets worldwide, whether Muslim militants or European leaders. According to James Bamford, author of two authoritative books on the agency, “The NSA's operation is eerily similar to the FBI's operations under J. Edgar Hoover in the 1960s where the bureau used wiretapping to discover vulnerabilities, such as sexual activity, to ‘neutralize’ their targets.”

Indeed, whistleblower Edward Snowden has accused the NSA of actually conducting such surveillance.  In a December 2013 letter to the Brazilian people, he wrote, “They even keep track of who is having an affair or looking at pornography, in case they need to damage their target's reputation.” If Snowden is right, then one key goal of NSA surveillance of world leaders is not U.S. national security but political blackmail -- as it has been since 1898. Such digital surveillance has tremendous potential for scandal, as anyone who remembers New York Governor Eliot Spitzer’s forced resignation in 2008 after routine phone taps revealed his use of escort services; or, to take another obvious example, the ouster of France’s budget minister Jérôme Cahuzac in 2013 following wire taps that exposed his secret Swiss bank account. As always, the source of political scandal remains sex or money, both of which the NSA can track with remarkable ease.

By starting a swelling river of NSA documents flowing into public view, Edward Snowden has given us a glimpse of the changing architecture of U.S. global power. At the broadest level, Obama’s digital “pivot” complements his overall defense strategy, announced in 2012, of reducing conventional forces while expanding into the new, cost-effective domains of space and cyberspace. While cutting back modestly on costly armaments and the size of the military, President Obama has invested billions in the building of a new architecture for global information control. If we add the $791 billion expended to build the Department of Homeland Security bureaucracy to the $500 billion spent on an increasingly para-militarized version of global intelligence in the dozen years since 9/11, then Washington has made a $1.2 trillion investment in a new apparatus of world power.

So formidable is this security bureaucracy that Obama’s recent executive review recommended the regularization, not reform, of current NSA practices, allowing the agency to continue collecting American phone calls and monitoring foreign leaders into the foreseeable future. Cyberspace offers Washington an austerity-linked arena for the exercise of global power, albeit at the cost of trust by its closest allies -- a contradiction that will bedevil America’s global leadership for years to come. To update Henry Stimson: in the age of the Internet, gentlemen don't just read each other’s mail, they watch each other’s porn. Even if we think we have nothing to hide, all of us, whether world leaders or ordinary citizens, have good reason to be concerned.

While Gemalto was indeed another casualty in Western governments’ sweeping effort to gather as much global intelligence advantage as possible, the leaked documents make clear that the company was specifically targeted. According to the materials published Thursday, GCHQ used a specific codename — DAPINO GAMMA — to refer to the operations against Gemalto. The spies also actively penetrated the email and social media accounts of Gemalto employees across the world in an effort to steal the company’s encryption keys. Evidence of the Gemalto breach rattled the digital security community. “Almost everyone in the world carries cell phones and this is an unprecedented mass attack on the privacy of citizens worldwide,” said Greg Nojeim, senior counsel at the Center for Democracy & Technology, a non-profit that advocates for digital privacy and free online expression. “While there is certainly value in targeted surveillance of cell phone communications, this coordinated subversion of the trusted technical security infrastructure of cell phones means the US and British governments now have easy access to our mobile communications.”

For Gemalto, evidence that their vaunted security systems and the privacy of customers had been compromised by the world’s top spy agencies made an immediate financial impact. The company’s shares took a dive on the Paris bourse Friday, falling $500 million. In the U.S., Gemalto’s shares fell as much 10 percent Friday morning. They had recovered somewhat — down 4 percent — by the close of trading on the Euronext stock exchange. Analysts at Dutch financial services company Rabobank speculated in a research note that Gemalto could be forced to recall “a large number” of SIM cards. The French daily L’Express noted today that Gemalto board member Alex Mandl was a founding trustee of the CIA-funded venture capital firm In-Q-Tel. Mandl resigned from In-Q-Tel’s board in 2002, when he was appointed CEO of Gemplus, which later merged with another company to become Gemalto. But the CIA connection still dogged Mandl, with the French press regularly insinuating that American spies could infiltrate the company. In 2003, a group of French lawmakers tried unsuccessfully to create a commission to investigate Gemplus’s ties to the CIA and its implications for the security of SIM cards. Mandl, an Austrian-American businessman who was once a top executive at AT&T, has denied that he had any relationship with the CIA beyond In-Q-Tel. In 2002, he said he did not even have a security clearance.

AT&T, T-Mobile and Verizon could not be reached for comment Friday. Sprint declined to comment. Vodafone, the world’s second largest telecom provider by subscribers and a customer of Gemalto, said in a statement, “[W]e have no further details of these allegations which are industrywide in nature and are not focused on any one mobile operator. We will support industry bodies and Gemalto in their investigations.” Deutsche Telekom AG, a German company, said it has changed encryption algorithms in its Gemalto SIM cards. “We currently have no knowledge that this additional protection mechanism has been compromised,” the company said in a statement. “However, we cannot rule out this completely.”

Update: Asked about the SIM card heist, White House press secretary Josh Earnest said he did not expect the news would hurt relations with the tech industry: “It’s hard for me to imagine that there are a lot of technology executives that are out there that are in a position of saying that they hope that people who wish harm to this country will be able to use their technology to do so. So, I do think in fact that there are opportunities for the private sector and the federal government to coordinate and to cooperate on these efforts, both to keep the country safe, but also to protect our civil liberties.”

The public records disclosure comes as government spying and criticism of the National Security Agency’s surveillance program has reached a fever pitch. However, a little-known and rarely, if ever, enforced law from 1878 distinguishes the spying under Panagacos from that of the NSA. The Posse Comitatus Act prohibits the military from enforcing domestic laws on U.S. soil by making such actions a Gross Misdemeanor, yet to-date no official has been prosecuted under the Act. Instead of conceding to the violations, the Army is currently using the Panagacos case to try to seal nearly 10,000 pages of documents, many of which are incriminating and embarrassing to the government. The legal effort to unseal those documents will play out over the next few weeks. The Obama Administration tried to dismiss the Panagacos lawsuit, but in a Ninth Circuit decision from December 2012 the court rejected the government’s arguments, ruling that allegations of First and Fourth Amendment violations were “plausible,” and ordered the case to proceed to trial. The lawsuit was filed on behalf of seven PMR members who sought to oppose the wars in Iraq and Afghanistan through nonviolent civil disobedience and is being heard by U.S. District Court Judge Ronald B. Leighton. In addition to Towery, named defendants in Panagacos include Thomas Rudd, one of Towery’s superiors at Joint Base Lewis-McChord, the U.S. Army, Navy, and Coast Guard, as well as certain officials within its ranks, the City of Olympia and its police department, the City of Tacoma and its police department, Pierce County, and various personnel from those jurisdictions.

Panagacos v. Towery is currently in the discovery stage and is scheduled to go to trial in June 2014. Further information: Recently disclosed Towery email Panagacos lawsuit complaint Domestic terrorism dossiers on plaintiffs

The Obama administration declines to discuss the scale of incidental collection. The NSA, backed by Director of National Intelligence James R. Clapper Jr., has asserted that it is unable to make any estimate, even in classified form, of the number of Americans swept in. It is not obvious why the NSA could not offer at least a partial count, given that its analysts routinely pick out “U.S. persons” and mask their identities, in most cases, before distributing intelligence reports. If Snowden’s sample is representative, the population under scrutiny in the PRISM and Upstream programs is far larger than the government has suggested. In a June 26 “transparency report,” the Office of the Director of National Intelligence disclosed that 89,138 people were targets of last year’s collection under FISA Section 702. At the 9-to-1 ratio of incidental collection in Snowden’s sample, the office’s figure would correspond to nearly 900,000 accounts, targeted or not, under surveillance.

Another firm selling similar equipment is VASTech, based in South Africa, which has a system called Zebra. Potential buyers are told it has been designed to help "government security agencies face huge challenges in their combat against crime and terrorism".VASTech says Zebra offers "access to high volumes of information generated via telecommunication services for the purposes of analysis and investigation".It has been designed to "intercept all content and metadata of voice, SMS, email and fax communications on the connected network, creating a rich repository of information".

It is now possible, from a single laptop computer, to locate where a mobile phone is calling from anywhere in the world, with an accuracy of between 200 metres and a mile. This is not done by attaching probes, and it is not limited to the area where the laptop is working from. The "cross border" system means it is now theoretically possible to locate a mobile phone call from a town abroad from a laptop in London.

At a recent hearing of the Privacy and Civil Liberties Oversight Board, administration lawyers defended their latitude to perform such searches. The board is scheduled to deliver a report on the legal authority under which the communications are collected, Section 702 of the Foreign Intelligence Surveillance Act (Fisa), passed in 2008. Wyden and Colorado Democrat Mark Udall failed in 2012 to persuade their fellow Senate intelligence committee members to prevent such warrantless searches during the re-authorisation of the 2008 Fisa Amendments Act, which wrote Section 702 into law. Dianne Feinstein, the California Democrat who chairs the committee, defended the practice, and argued that it did not violate the act’s “reverse targeting” prohibition on using NSA’s vast powers to collect content on Americans.

Much of the NSA's bulk data collection is covered by section 702 of the Fisa Amendments Act. This allows for the collection of communications – content and metadata alike – without individual warrants, so long as there is a reasonable belief the communications are both foreign and overseas.The communications of Americans in direct contact with foreign targets can also be collected without a warrant, and the intelligence agencies acknowledge that purely domestic communications can also be inadvertently swept into its databases. That process is known as "incidental collection".Initially, NSA rules on such data prevented the databases being searched for any details relating to "US persons" – that is, citizens or residents of the US. However, in October 2011 the Fisa court approved new procedures which allowed the agency to search for US person data, a revelation contained in documents revealed by Snowden.

The ruling appears to give the agency free access to search for information relating to US people within its vast databases, though not to specifically collect information against US citizens in the first place. However, until the DNI's disclosure to Wyden, it was not clear whether the NSA had ever actually used these powers.On Tuesday, Wyden and Udall said the NSA’s warrantless searches of Americans’ emails and phone calls “should be concerning to all.” “This is unacceptable. It raises serious constitutional questions, and poses a real threat to the privacy rights of law-abiding Americans. If a government agency thinks that a particular American is engaged in terrorism or espionage, the fourth amendment requires that the government secure a warrant or emergency authorisation before monitoring his or her communications. This fact should be beyond dispute,” the two senators said in a joint statement.

They continued: “Today’s admission by the Director of National Intelligence is further proof that meaningful surveillance reform must include closing the back-door searches loophole and requiring the intelligence community to show probable cause before deliberately searching through data collected under section 702 to find the communications of individual Americans."

When it came to judging the necessity and proportionality of what they were allowed to look for, would-be American users were told it was "your call".The Guardian understands that a total of 850,000 NSA employees and US private contractors with top secret clearance had access to GCHQ databases.

For the 2 billion users of the world wide web, Tempora represents a window on to their everyday lives, sucking up every form of communication from the fibre-optic cables that ring the world.The NSA has meanwhile opened a second window, in the form of the Prism operation, revealed earlier this month by the Guardian, from which it secured access to the internal systems of global companies that service the internet.The GCHQ mass tapping operation has been built up over five years by attaching intercept probes to transatlantic fibre-optic cables where they land on British shores carrying data to western Europe from telephone exchanges and internet servers in north America.This was done under secret agreements with commercial companies, described in one document as "intercept partners".The papers seen by the Guardian suggest some companies have been paid for the cost of their co-operation and GCHQ went to great lengths to keep their names secret. They were assigned "sensitive relationship teams" and staff were urged in one internal guidance paper to disguise the origin of "special source" material in their reports for fear that the role of the companies as intercept partners would cause "high-level political fallout".

The GCHQ documents that the Guardian has seen illustrate a constant effort to build up storage capacity at the stations at Cheltenham, Bude and at one overseas location, as well a search for ways to maintain the agency's comparative advantage as the world's leading communications companies increasingly route their cables through Asia to cut costs. Meanwhile, technical work is ongoing to expand GCHQ's capacity to ingest data from new super cables carrying data at 100 gigabits a second. As one training slide told new users: "You are in an enviable position – have fun and make the most of it."

The categories of material have included fraud, drug trafficking and terrorism, but the criteria at any one time are secret and are not subject to any public debate. GCHQ's compliance with the certificates is audited by the agency itself, but the results of those audits are also secret.An indication of how broad the dragnet can be was laid bare in advice from GCHQ's lawyers, who said it would be impossible to list the total number of people targeted because "this would be an infinite list which we couldn't manage".There is an investigatory powers tribunal to look into complaints that the data gathered by GCHQ has been improperly used, but the agency reassured NSA analysts in the early days of the programme, in 2009: "So far they have always found in our favour".

Historically, the spy agencies have intercepted international communications by focusing on microwave towers and satellites. The NSA's intercept station at Menwith Hill in North Yorkshire played a leading role in this. One internal document quotes the head of the NSA, Lieutenant General Keith Alexander, on a visit to Menwith Hill in June 2008, asking: "Why can't we collect all the signals all the time? Sounds like a good summer project for Menwith."By then, however, satellite interception accounted for only a small part of the network traffic. Most of it now travels on fibre-optic cables, and the UK's position on the western edge of Europe gave it natural access to cables emerging from the Atlantic.

The processing centres apply a series of sophisticated computer programmes in order to filter the material through what is known as MVR – massive volume reduction. The first filter immediately rejects high-volume, low-value traffic, such as peer-to-peer downloads, which reduces the volume by about 30%. Others pull out packets of information relating to "selectors" – search terms including subjects, phone numbers and email addresses of interest. Some 40,000 of these were chosen by GCHQ and 31,000 by the NSA. Most of the information extracted is "content", such as recordings of phone calls or the substance of email messages. The rest is metadata.

"The criteria are security, terror, organised crime. And economic well-being. There's an auditing process to go back through the logs and see if it was justified or not. The vast majority of the data is discarded without being looked at … we simply don't have the resources."However, the legitimacy of the operation is in doubt. According to GCHQ's legal advice, it was given the go-ahead by applying old law to new technology. The 2000 Regulation of Investigatory Powers Act (Ripa) requires the tapping of defined targets to be authorised by a warrant signed by the home secretary or foreign secretary.However, an obscure clause allows the foreign secretary to sign a certificate for the interception of broad categories of material, as long as one end of the monitored communications is abroad. But the nature of modern fibre-optic communications means that a proportion of internal UK traffic is relayed abroad and then returns through the cables.

British spy agency collects and stores vast quantities of global email messages, Facebook posts, internet histories and calls, and shares them with NSA, latest documents from Edward Snowden reveal

Following this ruling, based on the assumptions that federal law enforcement fundamentally act in good faith and that there may be a legitimate need for remote exploitation of computer data, the Justice Department sought to introduce changes to the rules that would overcome Smith’s objections. The proposed change to Rule 41(b) would allow magistrate judges “… to issue a warrant to use remote access to search electronic storage media and to seize electronically stored information located within or outside that district.” The Justice Department has indicated that it wants warrants permitting multiple computers to be searched at the same time, as well as permission to search all of the email and social media accounts accessible from a single computer. Such access would constitute a violation of the Electronic Communications Privacy Act, as the government, under the act, must make demonstrate probable cause to each targeted service provider and obtain and serve a warrant for each service provider. A warrant to search every account active on a computer would be actively bypassing the act’s numerous safeguards.

Privacy advocates fear that this rule change would allow prosecutors and the Justice Department to seek out magistrates likely to give them their requested warrants, creating a situation in which the federal government could have a “warrant shop” with just one judge for the whole of the nation. In light of allegations of federal government over-policing — including revelations of aggressive domestic and international electronic spying by the FBI and the National Security Agency — many advocates argue that an examination of the federal government’s commitment to the Fourth Amendment is needed. “The proposed amendment would significantly expand the government’s authority to conduct remote searches of electronic storage media,” the American Civil Liberties Union wrote in a memorandum early last month. “It would also expand the government’s power to engage in computer hacking in the course of criminal investigations, including through the use of malware and other techniques that pose a risk to internet security and that raise Fourth Amendment and policy concerns. “In light of these concerns, the ACLU recommends that the Advisory Committee exercise extreme caution before granting the government new authority to remotely search individuals’ electronic data.” The rules are scheduled to be discussed at the meeting of the Judiciary’s Committee on Rules of Practice and Procedure later this month.

That pseudo-explanation will likely do little to quell the security community’s doubts. Even if the hackers appeared to fail to use proxies on some occasions, it could still be very difficult to be sure those “real” IP addresses weren’t proxies themselves designed to serve as further misdirection. And a nagging loose thread remains that the Guardians of Peace hackers in their initial statements to Sony tried to extort money from the company before making any political demands. Sony’s Kim Jong-un assassination comedy “The Interview,” the suppression of which is believed by many to be the North Korean government’s motive in the hack, wasn’t even mentioned by the hackers until long after the intrusion was underway. Comey didn’t address that plot hole in the North Korean explanation in his speech.

FDD’s Long War Journal has maintained that the US military’s assessment of the state of play in Afghanistan’s districts is flawed. Our study estimates the Taliban controls 42 Afghan districts and contests (or influences) another 55. [Note: USFOR-A’s definition of “influence” matches our definition of “contested.” The term “influenced/contested” will be used for clarity to describe these districts. LWJ does not assess districts that are defined by USFOR-A as “contested,” which means neither the Taliban or Afghan government hold sway.] The number of Taliban controlled and influenced/contested districts has risen from 70 in October 2015 to 97 this month. Districts under Taliban command are typically being administered by the group, or the group controls the district center. Additionally, districts where the district center frequently changes hands are considered Taliban-controlled. In influenced/contested districts, the Taliban dominates all of the areas of a district except the administrative center.
