The New York Times has a big thumbsucker on WHY DID WE INVADE IRAQ which I think could be answered better by any left wing blogger from that period. It of course leaves out the role of The New York Times in making it happen.
But, really, as much as we like to make fun of Tom Friedman, he actually was most correct when he said we invaded Iraq to tell Iraqis, and the world, to suck on America's massive cock and balls.
Tom thought that was a good thing, however.
