Is he insane? I can't imagine why any British PM would tie his fortunes so closely to the most ignorant man ever to be President of the USA.

For him to argue this:

The world cannot stand by while Iraq is in "flagrant breach" of United Nations resolutions, the UK prime minister has said.

seems dangerous to me, given that one of the key "allies" of the US and UK in the Middle East is Israel, which is certainly in violation of a number of UN resolutions. It only makes the two countries look like hypocrites.

I'm not arguing that Iraq is country of peace and enlightenment, but I also don't see it as a country that threatens us enough to spend $50+ billion (more than the federal government's annual spending on primary and secondary education plus medical research) and risk thousands of American lives, to say nothing of de-stablizing much of the Middle East.
