I'm not sure Iran has many options for escalation left. Other than actually completing the nuke, which is something of a circular argument: they might escalate by building a nuclear weapon, but the only reason alleged for Israel escalating against them (which of course gets a free pass) is .. they're building a nuclear weapon. You can't escalate by doing something you're already doing. It only counts as escalation if they weren't building a nuke but Israel bombing their nuke programme forced them to build a nuke?
