General McChrystal Is Relieved of Command

General McChrystal is out as commander in Afghanistan, replaced by General David Petraeus, one of America's best-known military leaders.

In the White House, in Congress and on the battlefield, one side supports a troop surge followed by economic development and government reform. Can Petraeus implement the President's strategy? What about those, including Vice President Biden, who warn against bogging down in an unwinnable war?
