To say we "broke" Iraq is both inaccurate and demeaning to our troops. We saved Iraq from a monster. But in saving Iraq we are now responsible for ensuring that the life we saved is a life worth living.
We can start by turning Iran into a parking lot. Muslims hate us now, so why worry about it? I'd be willing to bet there's plenty of moderate Muslims that would be breathing a sigh of relief if we took out Mad Dog and his henchmen.
