A story in the Monday Stars and Stripes describes U.S. soldiers keeping their distance as Sunni and Shiite militias engaged in a Saturday night firefight in Mahmudiyah, Iraq. Most interesting is the description of militia members concealing weapons from U.S. soldiers while on their way to the fight, alongside a description of a militia"operating openly in Mahmudiyah in recent weeks."

The often-cited argument for a continued American presence in Iraq is that the country will descend into civil war if we leave. That argument misses the very real possibility that the civil war can happen -- and, in fact, is now happening -- without an American departure. If 26 million people decide to enter into a civil war, 130,000 outside troops are not going to stop them.

The whole story is short, and well worth the couple of minutes it would take to read.
