Dismantle, weaponize, or rebuild: Why the Iran nuclear threat isn’t going away

Bulletin, By Sina Azodi October 29, 2026

Iran now faces one of the most consequential nuclear decisions. In less than a year, the United States twice used military force to destroy key infrastructure and prevent Tehran from acquiring a nuclear weapon. These strikes have set Iran’s nuclear program back by severely degrading its nuclear enrichment capacity. But they have not eliminated the scientific expertise, industrial capacity, and political motivations that sustained the program for decades. Still, the attacks exposed the weakness of Iran’s previous strategy, which thought that by advancing its program but remaining below the nuclear threshold, Tehran was effectively deterring attacks from its adversaries. It failed.

Tehran now must choose between three main broad options: Dismantle its nuclear program, weaponize it, or rebuild its latent nuclear capacity while still being under the nuclear threshold. Despite its evident failure to deter foreign adversaries, the third path remains the most plausible. Dismantlement would require Iran to abandon three decades of technological investment in exchange for uncertain external guarantees of nuclear fuel delivery. Weaponization, meanwhile, would invite further military strikes and trigger a nuclear arms race in the Middle East. In contrast, rebuilding a latent capacity is already a tested strategy for Iran, allowing it to preserve its technological autonomy and leverage while avoiding immediate costs of acquiring a nuclear arsenal……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………..

Rebuilding. The third, and most likely, scenario is a return to pre-June 2025 threshold status, in which Iran reconstructs its nuclear capacity but refrains from crossing the finish line. Publicly available information indicates that Iran is rapidly rebuilding its pre-war nuclear infrastructure and working to finish a more fortified enrichment facility at Pickaxe Mountain. Rather than abandoning enrichment or rushing toward the bomb, Tehran could seek to restore a latent nuclear capability while making the program more resilient to future attack. Rebuilding the program may not represent a credible means of restoring deterrence, but an effort to preserve Iran’s nuclear options while avoiding the other alternatives………………………………………………………………………………………………………………………………………………

The destruction of Iran’s nuclear facilities may have bought time for Washington, but military force alone cannot resolve the Iranian nuclear challenge. If the United States is to prevent an Iranian nuclear arsenal, the central policy challenge is therefore to alter the incentives surrounding that choice. Any durable agreement would need to combine verifiable limits on enrichment and uranium stockpiles with robust inspections and tangible economic benefits for permanent restraint, while preserving substantial costs for a move toward weaponization. Without such an arrangement, repeated military strikes may delay Iran’s program without resolving the calculation that sustains it and could ultimately strengthen the argument inside Iran’s political system that only nuclear weapons can provide lasting security. https://thebulletin.org/2026/10/dismantle-weaponize-or-rebuild-why-the-iran-nuclear-threat-isnt-going-away/?utm_source=ActiveCampaign&utm_medium=email&utm_content=The%20Iran%20nuclear%20threat%20s%20not%20going%20away%20%20Here%20s%20why&utm_campaign=20261029%20Thursday%20Newsletter
