Religion only doesn't explain why the recent (post 9/11) surge in terrorists attacks. Also the world is far less religious than it was in the past, a very violent and vocal minority of people claiming to be religious are perpetrating these attacks while the majority of religious people condemn them. So it would be interesting to think about what changed, if not religion, that might cause this. I don't have a complete answer, not an expert in the subject but I'd venture to say that the actions of the West in the Middle East are one element of response.
