Why do Al queda and their islamists friends bomb and kill (mostly civilians) in Saudi arabia, pakistan, yemen, somalia, isreal, nigeria, india, phillipines, indonedsia, austrailia, etc etc
It's the US's fault!!! That's why!
It's an ideology bent on restoring a caliphate and expanding sharia law. Nonbelievers are less than human, even muslims who aren't strict don't count for much.
There is no denying that the US has made some mistakes, but to simply say it is because of the US is absurd. Muslims have been trying to spread by the sword since the lifetime of Muhammed. The last four hundrend years or so they have been too internally divided and too behind the west in science/technology to do much of anything. Hopefully if stays that way.
