YOU MUST REMEMBER THIS: William Safire makes a simple yet powerful argument in favor of our invasion of Iraq and against the sentiment that Bush/Blair lied to us about WMD there. It's a quick read, but if you can't be bothered the nut is right here in his closing:

When weighing the murky evidence of an aggressive tyranny's weapons, President Bush and Prime Minister Blair were obliged to take no chances. The burden of proof was on Saddam. By his contempt, he invited invasion; by its response, the coalition established the credibility of its resolve. There was no "intelligence hoax."
