Turkey committed genocide against the Armenians in the beginning of the last century; America committed genocide against Native peoples in the beginning of the modern era; Israel has been practicing a continuous campaign of genocide against Palestinians since the end of the last World War; and Saudi Arabia's intelligence director has been on record very recently as saying that he wants to wipe out Shiites.
So it's not like these countries and states are acting out of character when they throw their support behind genocidal terrorists like ISIL.
The dangerous thing is that two of these four genocidal states, Saudi Arabia and Turkey, are arming ISIL not just with conventional weapons but with chemical weapons that they will surely use on a mass scale.
"The Turk thinks he has a right to rule; but the only methods he knows are those which did not shock the conscience of anybody in the seventeenth century, but do shock the European conscience now; and hence his verdict was, "The way to get rid of the Armenian question is to get rid of the Armenians." - "The Cradle of Mankind: Life In Eastern Kurdistan" By The Rev. W. A. Wigram and Sir Edgar T. A. Wigram (1914).
