I think this is a totally reasonable response. Where I would push back is that we shouldn't separate Iran's status as a "disruptive force" from our own actions in the region going back to the immediate post-war period, especially the coup in Iran. We set the Islamic Revolution in motion.
American foreign policy proceeds from the assumption that we have the right to and should control ever region in the world. The world is our plaything. Iran's emergence as a sponsor of terrorism and hostile force in the region was a response to us.
IMO, any possibility for change in the region has to start with our acceptance that the Empire is over. Our role moving forward should not be as a military power, but as a force of economic and political development around the globe. In the Middle East, that starts by pursuing policies that empower the most moderate forces within hostile countries (the Iran nuclear deal being an example).
