A U.S. soldier in Afghanistan is accused of killing 16 civilians. He is thought to have left his base during the night and to have gone from house to house shooting people, including women and children.

Keeping in mind that these are early reports, which may be inaccurate — needless to say this is really, really bad, on every level. The Obama Administration has been trying to orchestrate a reasonably graceful endgame, and one suspects that’s been blown out of the water.

Recent polls suggests that more Americans than not want the U.S. to just haul itself out of Afghanistan and let the chips fall. The way things are going, that may be the best option.
