The main reason gas prices ( crude oil prices) are low is that the Saudi 's are worried about their wacky neighbor working on nuclear weapons and are getting the price of oil low so that they can't afford to keep working on it.
That is certainly part of it , the whole Shia vs Sunni thing and the proxy wars around it , someone is buying the ISIS oil that is being sold through Turkey as well and you can bet they aren't paying retail for it .
