You mean like Bin Laden? Oops.
There was no al Qaeda in Iraq before Bush invited them in. Saddam and Bin Laden were deadly enemies. If Bush had gotten Bin Laden, the public never would have let him invade. It's why he had to make the "bogus connection". It's called "hindsight".
Hate to break it to you but Bush never claimed AlQaeda was in Iraq before we invaded. He never claimed Saddam had anything to do with Sept 11 2001. He did claim, and it was proven by captured documents, that Saddam was attempting to lift sanctions, that he intended to return to mass production of Chemical and biological weapons, he intended to return to research on making a nuke.
The reality is that Bush ( if we are going to claim Presidents kill terrorists) killed more terrorists and more terrorist leaders then Obama.
There is evidence that Saddam was shopping around for a terrorist organization to carry out his attacks for him. Also proven by captured documents.
