The Phenomenon of ISIS

Excuse me but I would like to be spared sermonizing from one religion toward another about the need for tolerance and moderation, especially when the sermonizing religion is Christianity.  Every religion has within it a version of ISIS. And the West is the last to speak and preach on this because ISIS sprang from Saudi Arabia, a state whose very survival (read the last Snowden document on that) is a function of stated US and Western policy.
