You have to see this to know for definite that ISIS was created by the US, and of course, that has been done for Jewish interests.
Besides a few actual Muslim dupes, and there are quite a few, ISIS is mainly comprised of Kharijite takfiri fake Muslims. These come mainly from Saudi Arabia, which is ruled by a fake Muslim crypto-Jewish royal family installed by the British (even then under Jewish control) in the early 1900's, and the surrounding area.
Their actual beliefs, with them having been placed under sentence of death by mainstream Islamic law, have more in common with Judaism than Islam, hence their enthusiasm for slaughtering real Muslims wherever they go, and their wounded soldiers are rescued under fire on the battlefield by Israeli soldiers, taken to Israeli hospitals, given surgery for their wounds, and returned to the battlefield when they are ready to fight. ISIS fights for Israel and for Jewish world domination, even though they claim to have declared war on Israel, for disinformation purposes.
ISIS are in fact mercenaries who have been captured bearing arms supplied by Israel, they trade stolen oil through Turkey to Israel in exchange for arms and other supplies.
US special forces, serving Israeli Mossad officers and other Israeli armed forces personnel have been captured leading ISIS attacks. When ISIS attacks Europe, or Russia, it is Israel attacking Europe and Russia, but in Europe, where many of the politicians and even leaders of governments are Jewish, they hide what s really happening, and wish this to be seen as being done by 'Muslim' extremists.
This will be a little 'roof tapping' Israeli-style to try to intimidate President Putin for having dared to expel a Chabad Lubavitcher rabbi from Russia due to a perceived threat to Russian national security from that rabbi, Israel is letting Mr Putin know that there will be plenty more to follow if he does not allow the Chabad Lubavitchers, the most powerful and influential of all Jewish groups, to piss all over Russia.
