Nuclear weapons for all?

As Barack Obama becomes president, worry about a global breakdown of the system to prevent nuclear proliferation is mounting among nonproliferation specialists and foreign policy strategists across the political spectrum. Warns Joseph Cirincione, "We're on the verge of a system collapse." But Obama will find surprising bipartisan support for making a historic policy shift that until recently would have been seen as little more than a liberal pipe dream: coming out in favor of the eventual abolition of all nuclear weapons."This is the moment," says Cirincione.
