I read yesterday that there are 5.5 million Muslims in England. (Quite a large occupying army huh?) I think that's more than we have.
Number one, the FBI cannot capture Eric Rudolph, in North Carolina. The odds of capturing Bin Laden, anywhere, thus become diminished in my mind.
Second, Osama is the guy the USA trained and financed to successfully fend off the Soviet Union. He and his group are pretty much badasses, whether we like to think it, or not.
