Their hatred of us (western civilization) is older than the U.S. Nothing we have done in the past 100 years, let alone the war in Iraq, will ever change it. Historically the only thing that has ever kept militant islam in check has been fear. These people act like predatory animals (often worse actually) and anyone knows that such creatures are most dangerous twards humans (or people who act humane) when they lose their fear of us. I know it is not a very idealistic viewpoint, but it unfortunatly seems to be an accurate one.
It very well may be that the only way to prevent them from forcing their way on us is for us to impose ours on them.
