An economic collapse in the Arab lands would result in French Revolution style reaction. I am not one to wish death on others but anarchy over there is a richly deserved fate.
They have a lot of money and they keep books like a major league baseball team or a movie studio.
I predict there will be a partial collapse and by that I mean a political and economic breakdown that will threaten the security of a majority of Americans and the the Arabs, not Muslims, but specifically the Arabs will bail us out. But we will have to give them something in exchange.
Meanwhile we appear to be in a race against time (before our collapse) to create the environment where Arabs are put in direct danger from the Turks and the Persians. Eventually we have the leverage to extract a price for protection from them that would alleviate some of our financial distress. We have sent trillions of dollars over there in exchange for something now occupying the upper atmosphere - fully combusted petrol.
