Our government has cried "wolf" so many times, it gets a little hard to separate truth from politics. ISIS seems like a pretty radical group of extremists with little regard for human life when it comes to those who disagree with them. Past history seems to show that our involvement in the middle-east has a greater interest in oil supplies and the global economy over humanitarian interests. There are probably examples of much more brutal taking of lives and genocide in Africa that we conveniently ignore.
