What I find distressing is that a religion with over a billion followers is so quick to focus their hatred on everybody else!
Terrorism has traditionally been a common weapon for most religions at some point in history. It lends itself to fanaticism.
However, if a billion people really were completely flat out bonkers as some claim, the world would pretty much cease to exist.
Our pragmatic elders left many of them living in festering cesspools, where hatred towards us was encouraged in order to direct attention away from their own rulers. The Middle East imported the worst forms of governments the West produced & we turned a blind eye on it, because we were deeply involved in troubles of our own against the commies.
Many of the Arab governments were allies of the USSR. The fall of the USSR sort of allowed the cork to pop out of the bottle. Cleaning up the mess left to us by our elders has fallen to us & either we step up to the plate, accept our responsibility or IMHO, we deserve to lose.
