We invaded Iraq instead of Saudi Arabia where the hijackers came from. All we needed was an excuse
Not only that, since there really wasn't a clear link between 9/11 and Iraq, the Bush administration simply made an excuse (WMDs) to invade.
9/11 simply fell on Bush's lap at a time where he really wanted to invade Iraq anyway for financial reasons
Regardless of those mistakes, we long for Bush now, when you compare him with the orange agent.
