Reuters just posted a story on satellite imagery of Baghdad neighborhoods before the surge. 

The surge worked beyond our wildest dreams!  The mere rumour of the surge caused the Sunni and Shi'ia to kill each other in sufficient numbers to clear neighborhoods before the surge happened!  No, I wouldn't call that ethnic cleansing.  But it's JUST like how oil prices dropped with the rumour of domestic drilling.  Exactly like that.  And that's what John Sidney McCain III will do to fix the economy.  And solve our energy crisis.  So... yeah..  Let's drill!  John Sidney McCain III will win the War of Terror, and win the War on Energy, and he will lead Amerika to VICTORY!!!  VICTORY!!!  YOO ES AY!!!  YOO ES AY!!!  YOO ES AY!!!  YOO ES AY!!!
