I really don’t think The U.S and the U.N are trying to defeat ISIS, they merely want to get them under control. After all, the U.S has supported the Muslim Brotherhood of Egypt with tanks, jets, money and small arms. As Freedom stated, Al Qaeda, ISIS, Hamas, ISL are all one in the same, as the Muslim Brotherhood around the world goes.
Question: Why would we fund an organization in which we are trying to defeat?
Answer: We’re not trying to defeat them, it’s all for show, it’s called Grandstanding, a ploy to Awe the people.
