From all I've gathered, it is my belief that we could defuse this whole problem by simply getting our infidel asses out of Muslim countries.If they are telling us the truth about their hatred for us, that would remove that reason to hit us.

What we have been doing for the last 8 years hasn't worked, so why not try it?
