Analysis / Next Gen CommunityDisruption or Dismantlement: Diverging Assessments of Iran Nuclear StrikesByBailey SchiffPublished Jul 1, 2025Rising Lion and Midnight Hammer were widely hailed as a marvel of operational success, but the true measure of strategic success hinges on a murkier question: did the strikes merely delay Iran’s nuclear program or dismantle it for good?
Analysis / CommentaryThe Fallout Factor in Targeting Iran’s Nuclear ProgramByDoreen Horschig and Bailey SchiffPublished Jun 25, 2025Operation Midnight Hammer may mark the ceiling that conventional force can achieve against Iran’s nuclear program without triggering fallout. For Israel, this means future operations will likely involve sites that are more fortified or environmentally risky, or both.
Analysis / CommentaryWhat Operation Midnight Hammer Means for the Future of Iran’s Nuclear AmbitionsByJoseph RodgersPublished Jun 25, 2025Operation Midnight Hammer struck Iran’s key nuclear sites at Fordow, Natanz, and Isfahan using B-2s and Tomahawk cruise missiles. This effort aimed to destroy Iran’s uranium enrichment facilities, but its success is still to be determined.
Analysis / CommentaryIran and the Changing Character of the Nonproliferation RegimeByJoseph RodgersPublished Jun 20, 2025Rising tensions with Iran expose a volatile shift in the nonproliferation regime. As the regime’s normative power wanes, proliferation risks will rise, and military counterproliferation efforts will be more likely.
Analysis / CommentaryOptions for Targeting Iran’s Fordow Nuclear FacilityByHeather WilliamsPublished Jun 20, 2025There are five main options for targeting Iran’s Fordow facility: the GBU-57, sustained Israeli strikes, sabotage, nuclear weapons, and diplomacy. Each varies in its potential impact on Iran’s nuclear program and carries distinct risks of escalation and response.
Analysis / CommentaryThree Things Will Determine Iran’s Nuclear Future—Fordow Is Just One of ThemByHeather WilliamsPublished Jun 18, 2025Further strikes on Fordow, potentially with U.S. support, could be imminent, but their success is just one factor that will shape Iran’s nuclear future—along with possible withdrawal from the Non-Proliferation Treaty and support from Russia and China.
Analysis / Next Gen CommunityAmerica First, Allies, and Adversaries: Balancing Arms Control and Nonproliferation ByLachlan Mackenzie and Catherine MurphyPublished May 1, 2025President Trump appears willing to make significant concessions on regional security issues—potentially including support for key partners—to bring adversaries to the negotiating table. Three areas of U.S. policy will influence whether this approach raises the risks of allied proliferation: the administration’s approach to nuclear modernization, extended deterrence, and security concessions.
Analysis / Next Gen CommunityDespite Progress in Talks, the Threat of a Nuclear Iran LoomsBySyed Ali Zia JafferyPublished Apr 24, 2025While the ongoing Oman process between the U.S. and Iran is a positive development, the threat of Iran’s nuclearization still looms. There are three reasons why this is the case. First, the trust deficit between the two parties is hard to mitigate. Iran remembers Trump’s first term and his approach toward the Iran nuclear deal in particular and Iran in general. Second, Trump’s threats of military coercion will make Iran more vulnerable, with hardliners, including Ali Khamenei, likely to see nuclear weapons as their best deterrent. Third, the disintegration of its Axis of Resistance has left it with no other option but to get a deterrent of its own. All of this means that jingoism must give way to prudence and deft diplomacy.

Analysis / Next Gen CommunityA Choice of Nuclear Futures in Space ByLuke WidenhousePublished Sep 30, 2024In February, it was revealed that Russia has been developing a nuclear-armed anti-satellite (ASAT) weapon. Officials quickly issued reassurances that the technology had not been deployed and that it did not pose an imminent danger. While it is still not publicly known how far Russia is in the development of this capability, the news nevertheless underscores that trends are pointing to a future in space that is nuclear. But whether this future will involve the weaponized use of nuclear power in space remains an open question. As the United States seeks to curtail the proliferation of nuclear weapons in space, it must do so with a clear vision for the sort of nuclear future it would like to see in space. This article examines three possible such futures and the questions on arms control, nonproliferation, and extended nuclear deterrence that arise from them.
