Some Change to believe in

Let the neo-cons and paleo-cons howl, the world has changed and this is the wisest move he could make:

Barack Obama has demanded the Pentagon conduct a radical review of US nuclear weapons doctrine to prepare the way for deep cuts in the country's arsenal, the Guardian can reveal.

Obama has rejected the Pentagon's first draft of the "nuclear posture review" as being too timid, and has called for a range of more far-reaching options consistent with his goal of eventually abolishing nuclear weapons altogether, according to European officials.

Those options include:

• Reconfiguring the US nuclear force to allow for an arsenal measured in hundreds rather than thousands of deployed strategic warheads.

• Redrafting nuclear doctrine to narrow the range of conditions under which the US would use nuclear weapons.

• Exploring ways of guaranteeing the future reliability of nuclear weapons without testing or producing a new generation of warheads.

This is outstanding.
