How familiar are you with Michael Scheuer? He is the former CIA chief that led the Usama Bin Landen unit. I've read a lot of his stuff over the years and my opinions as it relates to terrorism align more closely with his. He has said a lot of controversial things, many of which I don't agree with. But I think he is a lot more thoughtful regarding the Islamic threat than our media and government is. I believe our government (and other governments across the world), use the threat of terrorism as a means to expand its power.
Anyways, here's a brief wikipedia summary of Scheuer's view on the war on terror - which I agree with much of it:
Additionally, Scheuer wrote an entire book about our foreign called "Imperial Hubris", which criticized foreign policy mistakes while he was still supporting the OBL team (he got in trouble for this). Osama bin Laden acknowledged the book in a 2007 statement, suggesting that it revealed "the reasons for your losing the war against us."
