And what nuclear disarmament with Iran? They're already disarmed. All of the highly enriched uranium has been given up. The JCPOA was specifically designed with the expectation of Iran cheating. That unilateral withdrawal is far worse for nuclear non-proliferation going forward. But this is completely consistent with John Bolton who was likewise involved when DPRK withdrew from the NPT.
