Claiming that Saddam had WMD.
- Going into war with Iraq without knowing there was a difference between Sunni and *****e Muslims and the Kurds.
There was plenty of intelligence before the war which cast doubt on Sadam having WMD but they ignored it because they came into power predisposed to go to war with Iraq.
The fact that they are still claiming there was some link between Sadam and Al Qaeda is a joke. The two groups hated each other.
The Bush presidency has been a disaster and I don't see how the next administration will be able to clean up the mess.
