WASHINGTON Internal documents indicate US President Obama pushed military advisers for an exit plan for the Afghan war, but it never came, a book by well-known American journalist Bob Woodward says. Woodwards new book, Obamas Wars, says Obama, given only options requiring a significant troop buildup, finally developed his own strategy that sought to limit the US involvement while avoiding talk of victory, The Washington Post reported on Wednesday. This needs to be a plan about how were going to hand it off and get out of Afghanistan, Obama was quoted as telling White House aides as he outlined his reasoning behind adding 30,000 troops for a short-term escalation. Everything were doing has to be focused on how were going to get to the point where we can reduce our footprint. Its in our national security interest. There cannot be any wiggle room. The book says Obama rejected the militarys request for 40,000 troops as part of an huge mission with no foreseeable end, telling Defense Secretary Robert Gates and Secretary of State Hillary Clinton in October 2009, Im not doing long-term nation-building. I am not spending a trillion dollars. Obamas Wars is the 16th book by Woodward, a Washington Post associate editor. Woodwards book portrays Obama and the White House as barraged by warnings about the threat of terrorist attacks on the US soil and confronted with the difficulty in preventing them. During an interview with Woodward in July, the president said, We can absorb a terrorist attack. Well do everything we can to prevent it, but even a 9/11, even the biggest attack ever . . . we absorbed it and we are stronger. But most of the book centers on the strategy review, and the dissension, distrust and infighting that consumed Obamas national security team as it was locked in a fierce and emotional struggle over the direction, goals, timetable, troop levels and the chances of success for a war that is almost certain to be one of the defining events of this presidency. Obama is shown at odds with his uniformed military commanders, particularly Admiral Mike Mullen, the Chairman of the Joint Chiefs of Staff, and General David Petraeus, head of US Central Command during the 2009 strategy review and now the top US and NATO commander in Afghanistan. Obamas Wars marks the 16th book by Woodward, 67, a Washington Post associate editor. In a dramatic scene at the White House on Sunday, Nov 29, 2009, Obama summoned the national security team to outline his decision and distribute his six-page terms sheet. He went around the room, one by one, asking each participant whether he or she had any objections - to say so now, Woodward reports. After Obama informed the military of his decision, Woodward writes, the Pentagon kept trying to reopen the decision, peppering the White House with new questions. Obama, in exasperation, reacted by asking, Why do we keep having these meetings?
