Here's a few terrorist acts that were not religious:

Timothy Mcveigh
Columbine
Waco Texas
Lee Harvey Oswald
The murder of Yitzhak Rabin
The attacks on a school in Belsan Russia
Poison gas on a Japanese subway

There are more that I can find but that's a start. It's sad that there are a lot crazies out there who do things like these with religious armor. Faithful pirates who feel that they are protected by their faith from the acts they commit. They attack their fellow citizens and leaders which makes it not about religion. I think it must be a security problem more than it is religion.

IMO it is not a religious war yet their faith has become part of their armor against committing crimes. The war is about land. They want the land back that was once theirs, and when they can't get it they turn to their faith for strength. They are also trying to conquer land in Africa and Asia. They want to bring their customs upon the land they want. So it be religion that is their biggest custom, but religion is not the purpose of their conquering desires. If anything it is their armor and weaponry.
