"Bush bears the blame for wasting trillions on wars that did nothing for anyone but killed hundreds of thousands."

You would have paid much more if he did nothing and let radical islam run rampant over the friendlies in the ME. Why do you think Obama doubled down on the program? We may see what would happen if Iran gets hit by Isreal. Think of everything in your life touched by oil and what happens if the oil markets are destabilized.
