al-sadr flees to teheran

I was fascinated by news reports that Moqtada Al-Sadr, leader of the anti-American (but mostly anti-Sunni) Mahdi Army, has fled to Iran for an indefinite period. Apparently someone forgot to tell him that the U.S. "surge" in Baghdad was not to be taken seriously. The less jovial news: Al-Sadr's presence, together with increasing evidence of Iranian involvement in killing U.S. troops, is likely to increase pressure for military action against Iran, a good idea if we're prepared for it but a bad idea if we're not. Right now, we're not.
