As the fifth anniversary of the terrorist attacks on September 11, 2001, approaches, the Bush administration wants to develop a new weapon in its anti-terrorism arsenal. Known as Prompt Global Strike, it would enable America to hit rogue states, terrorists or criminal organisations anywhere in the world quickly and with devastating force.
The plan is to spend US$500 million over the next two years taking some nuclear-armed ballistic missiles off submarines and replacing them with a similar number of long-range missiles carrying non-nuclear warheads that could strike any target in less than an hour.
Proponents of the scheme say it would allow the United States to react to a grave national-security threat without having to use nuclear weapons. But critical US lawmakers worry that other nuclear states, chiefly Russia and China, might be confused about the type of missile fired and its intended target. With only minutes to think, they could mistakenly conclude that they were under US nuclear attack, and retaliate with nuclear weapons.
In an attempt to allay these concerns, US Defence Secretary Donald Rumsfeld met his Russian counterpart, Sergei Ivanov, in Alaska recently. Mr Rumsfeld said he would be happy to see Russia do exactly as the US was planning to do - so that both countries would have an additional weapon available for pre-emptive strikes against mass-casualty terrorism or weapons of mass destruction. The risk of misunderstanding could be overcome by good communications and prompt notification of any launch, he said.
Russia is more receptive to the idea now than when it was first mooted in February. Mr Ivanov says detailed talks will follow.
Either way, this is another hi-tech response to terrorism. The US in Iraq, and Russia in Chechnya, have countered armed insurgency and political violence primarily by military means. US President George W. Bush has insisted since 9/11 that America is engaged in a 'war on terror'. This is a dangerous misnomer. It suggests military might is the solution when, in fact, the core of the struggle is ideological.
