When Donovan sang the song “And The War Drags On” more than four decades ago, he was referring to Vietnam, but one could be forgiven for thinking the song was written yesterday about Afghanistan. It has now been about five months since President Obama announced his strategy of increasing troops in Afghanistan and a vague commitment to withdrawing most U.S. troops beginning in mid-2011. The administration began back pedaling from that pledge almost immediately after Obama made it. With the deadline for withdrawing troops only slightly more than a year away, that goal seems more remote today than it did a year ago.
