Such as the 9/11 highjackers who were well educated, had no persecution? Sure, politics doesn’t help and is an influencing factor, but a moderate sane religion person doesn’t fly a plane into a building.
As I’ve said, actions derive from beliefs, and I doubt people would commit such terrorist acts without the utmost confidence in God, and the afterlife/paradise etc, and this of course comes from religion. Additionally, if invading someone’s country is enough to turn otherwise good moderate people to kamikaze death missions then where are the Tibetan Buddhist suicide bombers?
