Nobody claimed responsibility for the attacks in the oil-rich region, but concerns have been raised that insurgents have fled north to avoid the impending crackdown in Baghdad.
And there you have it - the problem with George Bush's surge. The insurgents just run away.
Sometimes I wonder - maybe this whole business about sending troops to Baghdad is one of those clever feints and all of the troops are really going to go somewhere else.
Or maybe the plan is that the insurgents do run away, and the extra troops keep Baghdad secure, thus giving the appearance of success.
Either way, I think it should be clear by now that fighting a guerrilla war with traditionally trained troops isn't going to work.
