Well, the fact that invading since Saddam is a dictator surely isn't a US affair since it doesn't affect American people. Thus it wasn't an American/British affair. So it's a world affair.
So why are only American/British (a token handful of others) troops in?
Who are the "token handful of others" that you refer to? Japan as Tech support who are actually helping rebuild, Australia as well. They aren't "token" you moron. Perhaps they aren't sending more fodder because their laws or intelligence wont permit it. Obligatory non-nationalistic stuff you ****[losesimpactwhencensoredhowannoying]
