"I'm trying to think differently," said the president in India. And he meant think differently about nuclear weapons.
For decades, the United States helped lead the nuclear non-proliferation movement. Twenty years ago, huge numbers of Americans were standing up for a nuclear freeze.
In India, George W. Bush thought differently, accepting India's nuclear weapons program and, some say, boosting it. Congress must now decide whether to endorse the deal.
But already, from India to Pakistan to the dreams of nuclear wannabes around the world, the 21st century looks like a time of nuclear opportunity.
Hear Jonathan Shell, Aston Carter, Richard Boucher and more talk about going from hopes of a freeze to fear of free-for-all nuclear weapons in a new century.
