I can only imagine the situation being different, but alas I have not researched. All I can say is, I trust what they say to be the reason more than what you claim to be the reason. In fact, you've literally just made a bunch of assumptions without any evidence.
Uh, the west have been in the middle east long before Islamic terrorism in the west. That last sentence is quite funny though, "the power that we can bring". You mean taking 10 years to find one man who was in his house? Or being involved in a region for about 13 years, making no difference whatsoever?
