Thundarr,
ISIS is an organization that was created, financed, trained, and unleashed by the US, in order to infiltrate into Syria, and engage in a proxy war on behalf of US, also in order to out balance Iran's growing influence in the region, owing to our CRIMINAL AND IMMORAL WAR IN IRAQ. The goal of the war in Syria, is to replace Assad. Let us see, who is more dangerous now. The entire military-industrial complex of the US or ISIS, Al Quada, AL Nusra, and othe smaller terrorist organizations. Religion is just a tool for these organizations to achieve their end result. The results that were ordered by their masters accross the ocean, and agreed upon by bloody dictatorial regimes of Saudi Arabia, Qatar, Turkey.
We created a monster, and now we fear mongering and brainwashing our population. If the US really wanted, ISIS would cease to exist in a very short time.
Every week Trump opens his big mouth and says that we should have taken Iraqi oil. Excuse me, but last time I checked Iraq was a souvereign state, unapologetically destroyed by the US. The Government and the people of Iraq, should decide how that country is going to use its natural resources.
Do you know who many recruits ISIS will get just out of this statement and the Muslim ban? A lot, trust me. They would say, see, these greedy Americans are trying to destroy our countries, attack Muslims, for our oil. Would it be a far reached idea. No.
Again I would re-post a Jewish proverb. "Don't pee on my leg and tell me it is raining."
