absolutely agreed.
Although the geostrategical goals cannot be left aside, there is also an important psychological factor. After the shock of the WTC-destruction, the Bush admin must have been under extreme mass psychological pressure to to something that is supposed to look like some sort of retaliation and that has a visibly bigger scale than the 9/11 terror acts. I believe that without the war in Iraq, Bush would not have been re-elected.
(But that is only a remote diagnosis by someone who has never been in the US)
These neocons are full of shit! Frames exist within larger frames. Draw a larger frame around your opponent's frame; he will appear wrong or insufficient. This is how wizards play.
