President Obama made a surprise trip to Afghanistan today, landing at Bagram Air Base north of Kabul. There he credited the troops with breaking the Taliban's momentum, saying the U.S. is quote "making important progress" in the war. Yet doubts persist, as the Taliban refuses to disappear, and corruption in the Afghan government thrives. Meanwhile, President Obama's deadline of next July for beginning to withdraw the troops is approaching. So tonight we ask you: Are we doing the right thing? Can the United States win the war in Afghanistan?
