Who else?  Russia.  The United States.  France.  Britain.  Israel.  To name a few.

Inshaa Allah (God Willing) I never have and never will deny the crimes, atrocities and abject stupidity of those calling themselves Muslims.  What  I will say is that such crimes, atrocities and stupidity constitute violations of authentic Islamic tenets, not fulfillment of them.  The Da'esh ("ISIS") and their ilk were my enemies before you ever heard of them.  They are no more "Islamic" than the KKK is "Christian".

Having said that, before you make such sweeping--and highly inaccurate--claims as to how we Muslims are the root of all evil in the world, may I suggest you look at the blood on your own hands.  I'm happy to provide body counts demonstrating that, from WWII up through the present, NO Muslim nation on earth nor all of them TOGETHER hold a candle to the western so-called "Christian" nations and Russia when it comes to bloodletting and warfare.
