It’s really simple the Islamist Jihadists which comprise a large percentage of the Muslims probable over 1/3 of the young men, like destroying everything that is not of their belief structure; so the make war, kidnap for ransom, take slaves and sell them (mostly women). be-head, kill, reape and plunder! They will do this in waves of violence just as they have always done this for the past 1400 years. There will be no end to this war on the world until the entire world is under Islam! If you think otherwise you are a fool!
