You can list a number of political and socio-economic reasons why Bush and his neocon allies decided to invade Iraq, but as for personal reasons -- and pardon the graphic characterization to follow -- this war, the reports they get, the videos they see, and the knowledge that they are responsible for all of it, makes their dicks harder than anything they can do with a woman (or a man, or a mule, even).  Ever wonder why Bush smirks so much while he's discussing the death and destruction of this war?  Now you know.  I'm surprised we haven't seen him humping the podium during some of his speeches.
