Kerry Says Killing Of Bin Laden Could Help Afghan Stability

Sen. John Kerry says the killing of Osama bin Laden is a potential game-changer that could lead to greater stability in Afghanistan and bringing U.S. troops home.

Kerry, in comments made as he opened a Senate Foreign Relations Committee hearing on Afghanistan, said the U.S. should be working toward a smaller force that puts Afghans in charge.

"It is fundamentally unsustainable to continue spending $10 billion a month on a massive military operation with no end in sight.  The good news is, I believe we don't have to," Kerry said.

However, Kerry said pulling out troops too quickly would be a mistake.
