He is to be replaced by Lt. Gen. Stanley A. McChrystal, a former commander of the Joint Special Operations Command. He served in Afghanistan as chief of staff of military operations in 2001 and 2002 and recently ran all commando operations in Iraq.

Forces under General McChrystal’s command were credited with finding and capturing Saddam Hussein and with tracking and killing Abu Musab al-Zarqawi, the leader of Al Qaeda in Mesopotamia. His success in using intelligence and firepower to track and kill insurgents, and his training in unconventional warfare that emphasizes the need to protect the population, made him the best choice for the command in Afghanistan, Defense Department officials said.

At the same time, he will be confronted with deep tensions over the conduct of Special Operations forces in Afghanistan, whose aggressive tactics are seen by Afghan officials as responsible for many of the American mistakes that have resulted in the deaths of civilians.

Pentagon officials have begun to describe Afghanistan as the military’s top priority, even more important than the war in Iraq. President Obama announced a major overhaul of American strategy in Afghanistan in March. Planned troop levels are expected to reach more than 60,000 Americans.

Mr. Ahmadinejad is seeking re-election on June 12. The letter he sent to the court was the first time he had intervened in a judicial case in his four years in office. Analysts said it would help his prospects if he could advance negotiations with the United States before the election.“Mr. Ahmadinejad wants to take serious steps towards improving ties with the United States before the elections,” said Ibrahim Yazdi, a political analyst in Tehran. “If he succeeds, it would be to his interest.”

If the United States were to establish an interest section in Tehran, for example, that would allow Iranians to obtain visas to the United States, without traveling to a third country, as they have to do now.

Something that sounded self-evident was in fact breaking a major taboo in US diplomacy. Washington had never before named Israel as a nuclear power. Every US administration has ignored, at least officially, Israel's nuclear arsenal, which it first produced in the late 1960s and has modernized and expanded ever since.

An agreement between the governments of Richard Nixon and Golda Meir obliged the US and Jerusalem to stay silent on the Israeli nuclear program. Every US president since has agreed that this was the best way to protect Israeli security. Israel refuses to this day to release any information on its nuclear weapons and in doing so has eluded any form of international inspections. The country has also avoided any non-proliferation talks. The logic is compelling: If something doesn't officially exist then it can't be counted, inspected or reduced.

Now Obama wants to revive it and he is doing so by keeping his distance from Israel. The outing of Israel as a nuclear power was just the pinnacle of a strategy that is aimed at giving America back its capability to act in the Middle East.

The White House had already made it clear that it would be making demands on the Israelis. The new Israeli Prime Minister Benjamin Netanyahu should make sure there is a complete halt to the building of settlements in the West Bank. During his recent visit to Turkey, Obama declared that the US "strongly supports the goal of two states, Israel and Palestine, living side by side in peace and security."

Ever since, relations between the US and Israel have become decidedly frosty. Israeli Environment Minister Gilad Erdan even went so far as to say that "Israel does not take orders from Obama." The old friends have never seemed so far apart.

On Monday the Times of London quoted Jordan's King Abdullah as saying that the US is planning to promote a peace plan for the Middle East that involves a "57-state solution" in which the entire Muslim world would recognize Israel. According to the newspaper, the king and President Obama had come up with the plan during his visit to Washington in April and details are likely to be thrashed out in the coming month, particularly when Israeli Prime Minister Netanyahu travels to Washington to hold talks with Obama next Monday.

The Times said that Israel may be offered incentives to freeze the building of settlements, including the offer by Arab states to grant visas to Israelis and to allow Israeli airline EL AL to fly through Arab air space.

SPIEGEL ONLINE: American politicians don't normally talk about Israeli nuclear weapons. Should the continue to be taboo? Jeffrey Herf: Of course. There is no reason to discuss Israel's nuclear weapons any more than there is reason to discuss the nuclear weapons of other American allies, such as Britain and France.

"I will have the opportunity to honour the memory of the six million Jewish victims of the Shoah," he said. "Sadly anti-Semitism continues to rear its ugly head in many parts of the world. This is totally unacceptable.

It is rumored that even the president's bodyguards are the same as those in Putin's time.

During his presidency Putin filled the Kremlin, government, and state enterprises with loyal cronies which leaves Medvedev with limited space to operate. "Words are good, but they don't change the system," says Rahr. "No one can say what kind of leverage Medvedev actually has. Perhaps he can free himself, but he has little room for maneuver." As far as Russia's power structure is concerned, the vital security and energy policies remains firmly under the control of Putin and Deputy Prime Minister Igor Sechin.

Senior Czech officials organising yesterday's summit openly acknowledged that the eastern partnership was aimed at countering Russia's influence in its backyard."Foreign policy is always about the projection of interests," said Alexandr Vondra, the outgoing Czech deputy prime minister. "You can project your interests, but you must give the respective countries the freedom to make choices."

The policy launched yesterday breaks new ground by seeking to entice the authoritarian regime of Alexander Lukashenko in Belarus. The instability in Georgia, the recent unrest in Moldova, and the permanent feuding among Ukraine's political elites all point to the formidable challenges for a policy that the European Commission describes as "a strategic imperative".

The new policy treats the six countries as a regional bloc, aiming to establish free trade areas between them and the EU, to tap their energy resources, and to promote human rights and democracy-building projects. But while the initiative is aimed at bringing the six countries in, it is also intended to keep them out. The declaration adopted yesterday was changed to call the six countries "east Europeans" rather than "Europeans" lest the latter description encourage applications to join the EU, as pushed by Ukraine and Georgia and opposed by western Europe.Eastern clamour for visa liberalisation to make it easier to travel to the EU was also blocked, with the issue parked for the long-term.

The Telegraph reported that Gordon Brown also claimed £153 twice for the same plumbing work at his constituency home - which No 10 said was done inadvertently and had been repaid. Justice Secretary Jack Straw claimed his entire council tax bill for his second home despite already enjoying a substantial discount from his local authority, worth a reported £1,500 a year.

Among other revelations, Ms Blears is said to have claimed for expenditure under the allowance on three different properties during the same year, spending £5,000 on furniture in three months. The Telegraph says by switching their designated second home between their London and constituency properties, Ms Blears and other MPs have been able to claim for household goods or other reimbursements for both.

Business Secretary Lord Mandelson claimed for improvements on his constituency home after he announced he was leaving Parliament to become an EU Commissioner. He later sold the property for a profit of £136,000. He rejected claims he used taxpayers' cash to "renovate" his home for profit, insisting the money was spent on essential maintenance. He said the Telegraph's report - which details a £1,500 gardening bill and £1,350 in house repairs - was presented to provoke public anger. "The fact is that these allowances would not have been paid if they weren't within the rules," he told BBC Radio Scotland's Good Morning Scotland programme.

Netanyahu has been aware of the letter's content for some time, according to his senior adviser, Ron Dermer. Dermer said that despite the letter's language, the important issue was that of underlying policy. var adsonar_placementId=1392266; var adsonar_pid=952767; var adsonar_ps=10912223; var adsonar_zw=200; var adsonar_zh=200; var adsonar_jv='ads.adsonar.com'; "On the substance, I don't think there's a difference in our position and the position of AIPAC," he said.

It is understood that the letter is being advanced despite its discrepancy with the prime minister's stated positions, because its content reflects both longstanding American policy and longstanding AIPAC positions.

Several versions of the letter are included in the kits being given out to participants in this week's AIPAC conference. One version, bearing a "United States Senate" letterhead, addressed to Obama, and left open for signature, states: "We must also continue to insist on the absolute Palestinian commitment to ending terrorist violence and to building the institutions necessary for a viable Palestinian state living side-by-side, in peace with the Jewish state of Israel." This version also gives explicit support for programs such as the US-supervised training of Palestinian Authority security forces. "The more capable and responsible Palestinian forces become, the more they demonstrate the ability to govern and to maintain security, the easier it will be for [the Palestinians] to reach an accord with Israel," it states. "We encourage you to continue programs similar to the promising security assistance and training programs led by Lieutenant-General Keith Dayton, and hope that you will look for other ways to improve Palestinian security and civilian infrastructure."

A second, similar version, also addressed to Obama and signed by staunchly pro-Israel Majority Leader Stony Hoyer and Republican Whip Eric Cantor, sets out a series of "basic principles" that, if adhered to, offer "the best way to achieve future success between Israelis and Palestinians." Among the principles cited is the requirement for the two parties to directly negotiate the details of any agreement, the imperative for the US government to serve as "both a trusted mediator and a devoted friend to Israel," and the need for Arab states to move toward normal ties with Israel and to support "moderate Palestinians." The clause that discusses statehood demands "an absolute Palestinian commitment to end violence, terror, and incitement and to build the institutions necessary for a viable Palestinian state living side by side in peace with the Jewish state of Israel inside secure borders." It continues: "Once terrorists are no longer in control of Gaza and as responsible Palestinian forces become more capable of demonstrating the ability to govern and to maintain security, an accord with Israel will be easier to attain."

A third version of the letter, addressed to their colleagues, is signed by Senators Christopher Dodd, Arlen Specter, Johnny Isakson and John Thune. It states that "we must redouble our efforts to eliminate support for terrorist violence and strengthen the Palestinian institutions necessary for the creation of a viable Palestinian state living side-by-side, in peace with Israel."

Netanyahu has long indicated that his concerns about Palestinian statehood are practical, rather than ideological - arising from the fear that a fully sovereign Palestinian state might abuse its sovereignty to forge alliances, import arms and build an offensive military capability to threaten Israel.

On Tuesday, Mr Saakashvili claimed his government had put down a brief mutiny among a tank battalion. Tbilisi had said it was part of a Russian-linked coup attempt to kill Mr Saakashvili. But opposition parties said the alleged mutiny was a deliberate attempt by the government to distract attention from the new phase of anti-government protests.

Anti-government protesters and police have clashed in the Georgian capital, Tbilisi, amid rising national tensions. Riot police used batons on protesters trying to enter a police compound where three people were being held over the alleged beating of a local journalist. The clashes were the first major unrest since anti-government demonstrations began in early April. They come a day after the authorities said they had thwarted an army mutiny at a base outside the capital.

In Nu'man, one of the villages the UN says is "living in limbo", the situation is particularly dire. The village is surrounded on three sides by Israel's West Bank barrier and on another by the Israeli settlement of Har Homa. The village entrance is blocked by an Israeli checkpoint to anyone other than Nu'man residents. Permits are not given for new homes in the village, and the younger generation is being forced out. Israel annexed Nu'man to Jerusalem after the 1967 war, but never gave its people Jerusalem residency.

Israel's hardline foreign minister, ­Avigdor Lieberman, lives in Nokdim, one of the Jewish settlements in the Beth­lehem area, some way to the east of Israel's barrier.

But Aipac delegates were told by the US vice-president, Joe Biden, that the administration favours "mutual respect" in dealing with Iran.Biden said the Israeli-Palestinian conflict strengthened Iran's strategic position and Israel must take concrete steps – including fulfilling often-broken commitments to stop the expansion of Jewish settlements – towards the creation of a Palestinian state.

Aipac's move to put pressure on members of Congress came at the end of its annual conference in Washington this week.Some of the loudest applause at the gathering came in response to calls for military attacks on Iran's nuclear facilities – something Netanyahu has attempted to portray as a more urgent issue than the Palestinian question.

The letter calls for the maintenance of the status quo, with an emphasis on Palestinian institution-building before there can be an end to Israeli occupation.It says the US "must be both a trusted mediator and devoted friend of Israel".

Last week, General James Jones, Obama's national security adviser, told a European foreign minister that the new administration would be "forceful" with Israel, according to a classified Israeli memo reported by the Ha'aretz newspaper.

Jones was quoted as saying that Obama believes Washington, the EU and moderate Arab states must define "a satisfactory endgame solution"."The new administration will convince Israel to compromise on the Palestinian question," he was quoted as saying. "We will not push Israel under the wheels of a bus, but we will be more forceful toward Israel than we have been under Bush."

During his election campaign, Obama alarmed Israel's hardline supporters by saying he regarded the lack of a resolution to the conflict as a "constant sore" that "infect[s] all of our foreign policy".

Aipac has moved to counter any new White House initiative by trying to mobilise Congress against it through the letter, written by two people seen as extremely close to the lobby group – Steny Hoyer, the Democratic majority leader in the House of Representatives, and Eric Cantor, the Republican whip.

The two men addressed an Aipac banquet attended by more than half the members of Congress on Monday, each standing in turn at a "roll call" of support for Israel.On the face of it, the letter is a call for a peace, but its specifics urge Obama to maintain years of US policy that has tacitly accepted Israeli stalling of peace negotiations.The letter says that "the best way to achieve future success between Israelis and Palestinians will be by adhering to basic principles that have undergirded our policy".These include "acceptance that the parties themselves must negotiate the details of any agreement" as well as demanding that the Palestinians first "build the institutions necessary for a viable state" before gaining independence.

His comments echoed the message from Chinese officials. Su Wei, a senior negotiator, told the Guardian last month that the US had made a "substantive change" under the Obama administration."The message we have got is that the current US administration takes climate change seriously, that it recognises its historical responsibility and that it has the capacity to help developing countries address climate change," Su said.

Miliband said he was encouraged by the change in tone since late last year in the country that emits more greenhouse gases than any other. "I think they're up for a deal. I get the strong impression that they want an agreement," he told the Guardian."They see the impact of climate change on China and they know the world is moving towards a low-carbon economy and see the business opportunities that will come with that."

"China used to think the developed world is not serious. That's what they were saying [at UN talks] in December," he said. "But now they know the US is on the pitch and ready to engage with them. It has made a real difference to what China is saying."

China wants developed nations to commit to more ambitious reduction targets, to share low-carbon technology and to set up a UN fund that would buy related intellectual property rights for use across the world. Beijing's position is complicated by the fact that it already owns a large share of the patents for wind and solar energy in developed nations.

Europe and the US accept the Chinese economy should be allowed to grow further, improving the living standards of its millions of poor, before it makes overall emissions reductions. Instead, the western nations are pushing for strong measures to improve efficiency and establish caps for certain industries. One possibility being considered by Chinese officials is to set a carbon intensity goal up to 2040 that would include energy efficiency, renewable energy, transport and afforestation.

Last month, the Tyndale centre published research showing that it was possible for China to begin reducing its total emissions from 2020.Government officials say that is unrealistic and China has so far resisted announcing a target for when emissions might peak. But the authorities tend towards the later end of the various academic forecasts of between 2020 and 2040.

Representatives for John C. Yoo and Jay S. Bybee, subjects of the ethics probe, have encouraged former Justice Department and White House officials to contact new officials at the department to point out the troubling precedent of imposing sanctions on legal advisers, said the sources, who spoke on the condition of anonymity because the process is not complete.

The legal analysis on interrogation prepared by a third former chief of the Office of Legal Counsel, Steven G. Bradbury, also was a subject of the ethics probe. But in an early draft, investigators did not make disciplinary recommendations about Bradbury.

Among other things, the draft report cited passages from a 2004 CIA inspector general's investigation and cast doubt on the effectiveness of the questioning techniques, which sources characterized as far afield from the narrow legal questions surrounding the lawyers' activities.

The government has warned that 500,000 people could try to leave if the peace deal formally breaks down, although the BBC's Mark Dummett, in Islamabad, says the army has not yet launched the offensive most are now expecting.

Afghan officials said Tuesday's violence broke out after more than 100 Taleban militants attacked a police checkpoint in Farah, in the far west of Afghanistan, killing three police.

The insurgents then reportedly moved to a nearby village where they killed three civilians who they accused of spying for the government. As the fighting continued, US airstrikes targeted militants thought to be sheltering in nearby houses. At least 25 Taleban fighters were reported to have died. But a growing number of reports from the area now suggest civilians were also seeking refuge in the buildings. Our correspondent in Kabul said local officials told him they saw the bodies of about 20 women and children in two trucks.

A spokeswoman for the International Committee of the Red Cross said a team of observers sent to the site of the air strikes saw houses destroyed and dozens of dead bodies, including women and children. "We can absolutely confirm there were civilian casualties," Jessica Barry said.

The US military said coalition troops were called to assist Afghan forces as they attempted to fight off an insurgent attack.
