If I actually believed your theory about the new "brown menace", I'd tell you to pull the IV of "super-soldier serum" they've got you on out of your arm and realize that if anything invading and occupying Iraq has had the opposite effect of what you're saying it was intended to prevent!
Unless it drew the combatants to Iraq (which is what has indeed happened). There are barely any comabants that are of Iraqi descent. Most are from the outlying countries; presumably (according to the latest intel) financed by the aforementioned countries. Now, if we have the ability to fight out enemies on foreign soil as opposed to at home as well as bring democracy to a country that was run by a sadistic dictator, don't you think that would be better than waiting, sitting on our hands until it (another attack) happens again?
Wow, so in fact Rumsfeld, Cheney, Bush, et al. were actually future-telling geniuses that figured they'd flambe' their own party, 700,000 Iraqis, 5000 Americans, $3,000,000,000,000, and American hegemony on this master stroke? Wow, I'm starting to see where you're going with this. I'm thinking FOUR MORE YEARS!
