They think we're stupid, Strick (and they may be right). That's why they tried to make us believe, when we first started not finding the WMDs, that they had been snuck across the border into Syria. They don't care if the more discerning of the US population catches them in a lie. All they have to do is repeat the same lie often enough and most people in the US will believe them.

Take for instance the idea that Saddam was responsible for the 9/11 attacks. Just prior to the US starting the war with Iraq this last time, most people in the US believed that Saddam was responsible for 9/11. And quite a lot of them still do. That's how gullible the vast majority of the people in this country are. Bush's people know this and they use this gullibility to help them promote their agenda every chance they get. They count on it.

If you want to know what their agenda is, read the treatise from the Project for a New American Century. It spells things out pretty clearly.
