Our dependence on imported oil will only get worse before it gets better. If you think we have "pain" now, imagine if the oil supply from the ME was interrupted for any significant amount of time. It is going to take decades before we can lessen our dependence on foreign oil. We are not prepared for the kind of "pain" you are advocating. We are not going to get it on our terms.
In less than 50 years, the U.S. Census Bureau projects that immigration will cause the population of the United States to increase from its present 300 million to more than 400 million. Since the US consumes about 25% of today's global oil supply, imagine what it is going to be like with that increase of 100 million more Americans who will also be competing with the growing economies of China and India for energy sources.
No one is ever prepared for pain, or it wouldn't be called pain. Having it on our terms does not mean without pain. It means that if the pain cannot be avoided, at least get a better result for it.
For example if the SoH is going to get shut down, I would rather it be initiated by the West to cease Iran's nuclear ambitions, than by Iran to cement their nuclear ambitions (followed by subsequent closings to come).
