If only that were true. I doubt that Abdul the suicide bomber is on a philosophical quest to force our governments to destroy our freedom.. The mindset of these people is quite simple: their culture is under attack by our culture (which isn't "intentional", the 'Western' way of life is simply a better way of life from every point of view which allows our culture to contaminate theirs), they are poor, they have little/no hope for a better future. They don't have the means to respond in a traditional manner to the threat they perceive (like Russia, China or North Korea do) so they resort to these desperate and futile acts.
The terrorists want to kill us, they want us to fear them and to leave them alone. We're there mainly for the fossil fuel. That's it.
