Well, we spent 50% of annual GNP every year for four years. We have spent about 5% of annual GDP every year for about 6 years. Not to mention the body count during WWII was 400,000 over 4 years vs just over 4,000 dead over 6 years for the War on Terror.
I'd much rather we have gone into a war mode and done things right, rather than having the American public so divorced from the war. I'm eager to see what happens in 2008, after the Sadr ceasefire expires, etc. I hope we find that it was all worth it.
