"Machines lack morality and mortality, and as a result should not have life and death powers over humans,"

"States are working towards greater and greater autonomy in weapons, and the potential is there for such technologies to be developed in the next 10 or 20 years,"

Unmanned aerial vehicles were intended initially only for surveillance, and their use for offensive purposes was prohibited, yet once strategists realised their perceived advantages as a means of carrying out targeted killings, all objections were swept out of the way.

This Chinese satellite navigation network will obviate the need to use the Pentagon-created and U.S.-run GPS system, which dominates location technology worldwide.

This strictly Chinese system, according to a defense tech expert in today's Wall Street Journal, "could help the Chinese military to identify, track and strike U.S. ships in the region in the event of armed conflict." It has already been used to coordinate the movement of Chinese troops.

The BNSS is not believed to be as accurate as the GPS system, but it may, in time, get there. Bedou, which means Big Dipper in Mandarin, is only the first step toward a global system, called Compass, which is slated to have 35 functioning satellites around the world by 2020.

France urged international financial bodies to fund a new era of global nuclear power on Monday and pitched its own reactor technology as the model to follow.     Welcoming delegates from 60 energy-hungry nations to a conference in Paris, President Nicolas Sarkozy said civil nuclear power had been unfairly passed over for World Bank development loans.    

He called on world and regional financial bodies to finance new nuclear projects in developing countries, and announced that France would set up an international institute to promote atomic technology.     "I can't understand why nuclear power is ostracised by international finance, it's the stuff of scandal," he said, urging the World Bank, the European Bank for Reconstruction and Development and others to do more.

"I have decided to change up a gear by creating an International Institute of Nuclear Energy that will include an international nuclear school," he said.     He said the French school would become the heart of an international network of institutes, beginning with a centre in Jordan.     "Other centres of nuclear training will be developed with French support, such as the Franco-Chinese nuclear energy institute, in cooperation with the University of Guangzhou," he said.     France has the world's second largest nuclear sector and generates a greater proportion its own electricity through nuclear power than any other economy -- around 75 percent of its needs.     It has also made the export of nuclear technology an economic priority.

A series of online attacks on Google and dozens of other American corporations have been traced to computers at two educational institutions in China, including one with close ties to the Chinese military, say people involved in the investigation.

the attacks, aimed at stealing trade secrets and computer codes and capturing e-mail of Chinese human rights activists, may have begun as early as April, months earlier than previously believed.

Computer security experts, including investigators from the National Security Agency, have been working since then to pinpoint the source of the attacks. Until recently, the trail had led only to servers in Taiwan.

Iran's president has unveiled new "third-generation" centrifuges that its nuclear chief says can enrich uranium much faster than current technology.The centrifuges would have separation power six times that of the first generation, Ali Akbar Salehi said in a speech marking National Nuclear Day.

The new technology could shorten the time it takes to build a nuclear bomb.

In a BBC interview, the former head of the International Atomic Energy Agency (IAEA), Mohamed ElBaradei, said Western nations were seeking harsher sanctions "out of frustration". "I don't think Iran is developing, or we have new information that Iran is developing, a nuclear weapon today," he said. "There is a concern about Iran's future intentions, but even if you talk to MI6 or the CIA, they will tell you they are still four or five years away from a weapon. So, we have time to engage." He said it was a "question of building trust between Iran and the US". "That will not happen until the two sides sit around the negotiating table and address their grievances. Sooner or later that will happen."

a nuclear-armed Iran would raise for the Arab states the question of an "Arab bomb," given that the main non-Arab actors in the region -- Israel, Iran and the US -- would all have nuclear weapons under this scenario. Large states like Egypt or Saudi Arabia might therefore want to join the club.

In a world with more than 20 nuclear weapons states, it would be far more difficult to defuse conflicts. It would be an immensely dangerous world.

SPIEGEL ONLINE: Would the traditional deterrence mechanisms no longer function in that case? Janning: They would still function for the "old" nuclear powers. These states are, and will continue to be, capable of striking any location on the Earth's surface with nuclear weapons to the extent that life can no longer exist there any more. That is not, however, the case for the "new" nuclear powers. They can only threaten an attacker with the risk of a retaliatory nuclear strike whose effect is not entirely predictable. This in itself is likely to negatively affect the so-called "extended deterrence" of today's nuclear powers. (Editor's note: Under extended deterrence, a state threatens nuclear retaliation in the event of a nuclear attack on its allies e.g. other NATO members.) In other words, America's allies can no longer be certain that a US security guarantee offers them adequate protection against a nuclear attack by third parties. Washington might, after all, decide that the cost of intervening under these conditions is just too high.
