Iraq would not have devolved into the failed state it is had not Bush made invading it and overthrowing Sadaam his top priority from the first cabinet meeting forward. Had it not been his top priority the AUMF would never have even been considered and Iraq would still be a functioning state. Terrorist organizations flourish in lawless states ala Iraq after the chaos of the invasion and the displacement of half it's population. Bush owns the mess in Iraq because it only happened because he made it such a priority. Bush and Tony Blair lied and now Humpty Dumpty is impossible to put back together again.
