Cheney's denial & blame shifting are shameful. This thread shows he's not alone in that, either. Some of y'all seem to think that Obama invaded Iraq & fucked up the occupation, given the way you're putting the blame on him.
Obama's part is that he followed through on the air tight agreement GWB signed in 2008. Iraq became a sovereign nation again in Dec 2011 when American troops left on schedule as stipulated in that agreement. The notion that we should go back now after the total cock-up of invading in the first place is absurd. We never belonged there.
It's true- we broke it, under some of the flimsiest justifications for pre-emptive war ever dreamed up. The silly idea that we can now fix it is just more of the same arrogance we followed when we broke it.
