President Barack Obama recently announced that he was determined to 'finish the job' in Afghanistan, and aides signaled to allies that he would send as many as 25,000 to 30,000 additional American troops there. Obama will formally announce his decision in a national address at 8 p.m. Tuesday from the Military Academy at West Point. As casualties mount on both sides, 2009 is shaping up to be the deadliest year yet for coalition troops - twice as deadly as 2008. American and Afghan officials have been encouraged by the recent rise of independent anti-Taliban militias in Afghanistan, even though their emergence is recent and supporting them raises fears of the consequences of arming and training Islamic militants. Collected here are images of the country and conflict over the past month, part of an ongoing monthly series on Afghanistan. (42 photos total)
