"More time"
A lot of people have developed the odd idea that if we hadn't invaded Iraq, everything else would have gone just swell. Libya would have disarmed anyway, Syria would have left Lebanon, Iran wouldn't be pursuing nuclear weapons, and Saddam and his lunatic sons would have taken up knitting after the sanctions were dropped.
Oh, and all the psycho Islamists heading to Iraq to fight the Great Jihad would all be bagging groceries right now instead of heading for Afghanistan.
It might be fun to go down the extensive list of the wanted terrorists in Iraq, and see how many of them were just peaceful civilians prior to March of 2003.
