Absolutely none of that would happen. It's in Iran's interests to keep the oil flowing at a fee that everyone can stomach and that doesn't offend the sensibilities. $1 a barrel for a year of unprovoked war crimes costing them hundreds of billions of dollars, with the cost effectively shared by all, fits this description. Nor has Iran responded with the kind of zero-sum, suicidal, totalitarian foreign policy that is always attributed to them by their enemies. Serious commentators have all remarked at how restrained they've been during this war. It's almost as though sane people who intend to come to a realistic agreement that everyone can live with are running their foreign and defence policies.
