To guarantee re-election, stupid! Rove must be laughing at us all. Would we invade another country just to get re-elected? Well, why not? A massively flagging economy, burgeoning deficits, rampant unemployment, Bush was basically guaranteed to get booted from office without another war or another major attack on US soil. The US has never dumped a 'wartime president', so why would we start now?
I've probably pointed this out before, but Justin Raimondo over at AntiWar.com wrote my favorite article on why we invaded Iraq. He doesn't think oil had anything to do with it - on that count I think he's wrong - but the other stuff is pretty enlightening.
