I don't think the Iranians will attack any Israeli nuclear facilities for fear of nuclear retribution. But a cornered animal can do unexpected things if its survival is at risk. That type of, "If I am going down, I will take you with me attitude." The same could be said for Iran's oil fields. "If we can't have them, neither will you. We will bomb and burn the whole lot." The Israelis couldn't care less if Iran is turned to dust, but if Trump does all this and can't get the oil it is a waste of time. Cuba's oil is only small potatoes compared to Iran's.
