I'm grateful that the military surge has reduced violence in Iraq.  But it's discomforting to see John McCain, or any politician for that matter, trumpeting it as an unqualified success, and claiming credit for it.   
If John McCain wants to take credit for "the surge", let him. But in doing so, he has to claim responsibility for the entire war in Iraq. Because it was his judgment that led our troops full steam ahead into this, the worst foreign policy blunder in the history of America.   He can't just ride on the coattails of a specific period of time--the last 12 months.  He has to own all five years.  
Remember,  success has many fathers.  But failure is an orphan. 
IMHO,  the Iraq body count project is the only visual representation that comes close to depicting that failure.
