There goes another justification
The talking point from the right on Iraq there, for a while, was "we invaded to bring them democracy".
Well, looks like that's no longer the case:
President George W Bush promised in a pre-Chistmas speech that America will leave Iraq only when “victory” has been achieved, but the term is being quietly redefined.
Dov Zakheim, a senior Pentagon official during Bush’s first term in office, said: “The goal is not democracy, it is a united Iraq that doesn’t bother its neighbours. There is no law that says American troops have to be in the most hostile areas.”
So we spent all that money and blood to get an Iraq that "doesn't bother its neighbors"... which they weren't doing to begin with.
