Russia and the United States, the two former Cold War enemies, may still have enough of a nuclear arsenal to obliterate each other several times over, but today's signing of landmark arms reduction deal is still hugely significant.

First of all, it signals a rapprochement between Moscow and Washington after a period of tension. Secondly, it sets the stages fro future reductions of nuclear arsenals. Thirdly, and perhaps in the short term most importantly, it gives the Obama administration a certain moral legitimacy when asking Iran for nuclear containment.

Numbers aren't what make this START treaty pivotal – both Russia and the United States will reduce the number of deployed nuclear warheads to 1,550 – it's the symbolic message being sent to the world.

It also gives Barack Obama a significant foreign policy victory less than a year and a half into his presidency.

We are live in Prague with White House Correspondent Ed Henry and in Moscow with Matthew Chance for a look at this story from both the U.S. and Russian perspectives.

Also today, we are live in Kyrgyzstan for the latest on what is still an entirely confusing situation. After several days of violence, opposition leaders say they've toppled the government and are now in charge. But the man they say has been ousted, Kurmanbek Bakiyev, says he refuses to leave.

We'll also show you Tiger Woods' new television ad for Nike, featuring the voice of his deceased father. It's certainly generating a lot of talk. Already, late night talk show hosts have aired spoofs of the ad. We'll show you the one Jimmy Kimmel's team put together.

That plus the all the major news stories and how today's jobless claims numbers are affecting Wall Street.
