As a former Bush supporter and pro-Iraq war to the point that I enlisted and deployed 3 times, my position is somewhere between Paul's and Bush's. I don't think we can disengage, but clearly you can't hand democracy over to a people who don't know how to properly use a toilet. I think Reagan was also somewhere between Bush and Paul. Reagan was for a strong foreign policy but he didn't send troops to every craphole thinking he could change backwards cultures by goodwill.
That was the latest stated purpose for the invasion but was that the real purpose? It seems to me that the real purpose was just to bomb Iraq halfway back to the stone age so that it would be less of a threat to Israel.
