47 World Leaders Join Obama at Nuclear Summit

Just a week after the US and Russia agreed to cut nukes by a full 1/3, leaders from 47 countries around the world join President Barack Obama to diminish stockpiles of nuclear weapons and secure "loose nukes" that terrorists would love to get their hands on.

And on the first day of the summit, more good news: Ukraine has agreed to give up all of its weapons-grade uranium. Two major nuclear milestones in less than two weeks.

And now China has agreed to possible sanctions against Iran.
