Well, of course our foreign policy is to blame. If we went to Bin Laden and the Arab governments and worked out a plan to bomb Israel, turn over "palestine" to Arafat, give national praise to Allah, and a bunch of crap like that, then we would be at peace for at least 15 or twenty years, I bet.
Then when they demand we do away with elections and install some mullahs as our rulers, they could again blame our policies if we refused.
