Who cares what causes Islamic violence? This is like asking what causes rape!
Just kill those using violence and the cause will become less important.
Simple.
Kinda hard to kill them when the off themselves in the process of committing mass murder.
My solution is to hunt down their families and give ‘em a choice: Give us the recruiters, trainers, handlers, techs, and/or paymasters, or die to the last man, woman and child.
For some reason this gets me flamed...
To paraphrase Mao, Islamic Terrorists swim in a sea of Islamists. A large percentage of Muslims living in the west are Islamist. The more you allow in the west, the more terror there will be. But terror is not needed. In 100 years many more European countries will be Muslim if current trends hold in France, Russia, Spain, Macedonia. Others will need another 100 years beyond that.
