In short here's what Ron Pauls view on foreign policy is..
They don't attack us because of our freedoms or because we don't think like they do.. they attack us because we've been meddling around in the middle east for over 50 years. We've been bombing Iraq for 10 years, we've set up bases in Saudi Arabia which they call Holy Land, we've been messing with them for a long time. The CIA calls this blowback, it's in the 9/11 commission report, michael scheuffer supports this position (head chief of CIA Bin Laden Unit).. and even bin laden gave scheuffer a shout out in his video (if you don't believe me on why we hate you, maybe you'll believe an America).

We can't go around the world doing what we want, trying to impose our will on others, without inciting hatred.. that is the main motivation for September 11th and terrorist attacks. What would we think if another country like China came over here and started doing this to us? We would try to fight. Why aren't terrorists attacking other free countries like France or something? C'mon... thinking they attack us because of our freedoms is extremely dangerous thinking and very ignorant. It is better if we just came home and protected.. they wouldn't have an incentive to attack us and we'd be a lot less likely to even be attacked.. and we can spend all that TRILLIONS and TRILLIONS of dollars here protecting ourselves, our borders and helping our people here at home instead of wasting it overseas trying to police the world and build an empire. It is the ONLY economically feasible policy and the only sane and feasible foreign policy. Think about it guys.. do some research. We're going broke, we have to borrow billions of dollars each day from China, Japan, etc just to fund the war.. Our national debt is 9 trillion+. The dollar is getting weaker and weaker and we're printing money out of thin air. This defective foreign policy is costing us lives, money and the sacrifice of civil liberties here at home. It doesn't make sense.

BTW, Ron Paul voted to go after the terrorists after 9/11.. but he was the first to say NO to Iraq. Like I said, he has the only sane foreign policy and anyone who believes otherwise is brainwashed by the media and hasn't done enough research to know the truth.
