I think it might be a healthy exercise to consider that we, the West, HAVE been attacking Islam for some time now. OUR Weapon of Mass Destruction is the internet and mass media, and Joe Jihad objects more to Britney Spears than US support of Israel. If you consider how this impacts their culture, their Point of View is very understandable.
I'm interested in what leads you to this belief. Most of what I have read from Sageman, OBL's manifesto, etc. leads me to believe that Islamists object mainly to what they perceive as military/political domination of the Muslim world by nefarious Jewish/Western interests, leading to atrocities against defenseless Muslims, i.e. Israeli occupation in Palestine, Russia invasion of Chechnya, Serb attacks on Bosnia and Kosovo, Western sanctions vs Iraq, now U.S. occupation of Iraq, etc.
