Rich Lowry writes that

The Left needs to favor the Afghan war for political reasons as long as it is agitating against the Iraq war. But shouldn’t it oppose the Afghan war for all the same reasons it has opposed Iraq? Afghanistan is in a civil war; it has deep ethnic divisions; the war there has lasted longer than World War II and longer than the Iraq war; it has become a magnet for militants, as more and more of them are going to the Afghan theater rather than Iraq (where they have a good chance of being killed, while fighting for an unpopular cause); if Iraq was supposedly “unwinnable,” Afghanistan is an even tougher proposition; etc.

His Devil’s advocacy against continuing in Afghanistan is stronger than he thinks. The U.S. had a good reason to invade in 2001, though it would seem that the Bush administration was more interested in Iraq all along; but I can’t for the life of me imagine what we hope to accomplish by staying there.
