I don't believe it was that. Our first jaunt into Iraq, was a response to them invading Kewait, and threatening our supply of cheap oil. The second time, Was supposedly in response to 9/11. I personally think GWB used that as an excuse to go back and finish what his father had started. Incidentally, I think 9/11 was in response to American support of Israel.
Whatever provoked it, we were intent on knocking it down until Obummer got in with his Muslim Brotherhood policy.
