Iranian parliamentary hardliners have registered at least ten proposals to exit the NPT following 2025 military strikes and sanctions, with figures like Mahmoud Nabavian linking the calls to war costs and urging a nuclear doctrine shift. Senior officials including Mohsen Rezaei have conditioned any review on renewed U.S. aggression, while the government maintains its longstanding position against nuclear weapons development and has not advanced legislation. Active Qatari-mediated diplomacy, IAEA verification talks, and draft frameworks addressing enriched uranium stockpiles and sanctions relief favor continued treaty participation to avert escalation ahead of U.S. midterms. These factors underpin the 91.4 percent trader-implied probability against withdrawal before 2027, reflecting institutional barriers and preference for negotiated de-escalation over rapid exit.
