I knew ISIS is a conspiracy of high civilized countries like Israel. it's simple, if a country wants to create chaos, the easiest way is to do politics pitting. and then be an ISIS which super paranoid.
I don't know whether it was Israel which created the ISIS, but for sure they have been supporting the ISIS for quite some time. A few months ago, Israeli jets bombed the Syrian army positions (inside Syria), inorder to help the ISIS in the combat. Also, the ISIS has so far restrained from attacking Israel or the Jews.
