I don’t disagree with your assessment of attacking Iran, it would most likely lead to WWIII. But if a very targeted attack were to happen (as is Israel’s MO in the past), the oil production would not stop completely. Iran depends on oil just as much as we do, if not more so. Matter of fact, they are a huge importer of gasoline since their refining capacity isn’t much better than ours. Israel would attack their military, not the oil production. And their productions is just over 3 billion barrels/day, and while this is a large amount, it’s bump if taken totally off-line would be about $10 per barrel. I’d worry more about the impacts of pissing off China and Russia.
