The Phillipines and the Balkans show that the Islamists are on a worldwide march. Sooner or later they would have come after us anyway. IMHO, I'd rather take them out now than try to do so when they number 2 billion after they wipe out Europe and what's left of Africa.
Why not return to a policy of non-intervention, lead by example and allow no significant threat to the United States?
It seems to me that we are in the role of globocop to protect the interests of multinational corporations.
