The White House on Monday said that the administration of U.S. President Barack Obama is not considering leaving the war in Afghanistan. White House Press Secretary Robert Gibbs said that Obama is not considering leaving the failing war in Afghanistan, but he is in the middle of reassessing the U.S. policy in the war-torn country. Gibbs said it is clear that the United States cannot simply withdraw. The debate over whether to send as many as 40,000 more U.S. troops to Afghanistan is a major part of the strategy overhaul that senior administration policy advisers will consider this week as they gather for senior-level meetings on the war. The meeting comes at a pivotal time as the war is about to roll into its ninth year. Gibbs said the administration would brief leaders from both parties and key committee chairmen about any decisions that they make. The top three U.S. military commanders overseeing the war in Afghanistan, however, favor continuing the current fight against the Taliban, which could take as many as 40,000 additional U.S. troops.
