For @CarnegieEndow I wrote about the perils of nuclear ambiguity, and what Iran (and the world) can learn from the saga of Iraq's nuclear program. TLDR: playing political football with international oversight rarely ends well for anyone: carnegieendowment.org/resear…

We’re delighted to announce Avril Haines as the next president of the Carnegie Endowment for International Peace. One of the most respected national security leaders of her generation, Avril brings a deep commitment to public service and the values at the heart of our mission.

Iran’s nuclear program dominates conversations around nuclear risk in the Iran war. But there's also another big threat: attacks on civilian nuclear infrastructure – which aren't unique to the Iran war. @JDMenton explains why that's so dangerous (and why it could get worse).

Some thoughts for @CarnegieEndow about how the Iran War is surfacing nuclear risks that go beyond the standard emphasis on proliferation (and why questions about civilian nuclear power plants in conflict zones are unlikely to go away anytime soon) youtube.com/shorts/fLO47nwH4…

At Barakah NPP, I met the team that responded to the May 17 drone strike. Trained by the @IAEAorg, they demonstrated the professionalism, skills and preparedness that nuclear safety demands every day.

On Monday, 8 June, Director General @rafaelmgrossi briefed the Board of Governors on the IAEA’s efforts to support nuclear safety, security and safeguards in conflict-affected regions while expanding the benefits of nuclear science and technology around the world. The Board, which is one of the two policy-making bodies of the Agency, along with the annual General Conference of IAEA Member States, will convene all this week in Vienna.

Important, and underappreciated!
Say what you want, but Rubio has consistently demonstrated a stronger understanding of the specifics of Iran policy (esp. sanctions) than anyone else in the admin. When asked re: sanctions relief, he says that any relief offered to Iran will be conditional on Iran taking verifiable steps on its nuclear program, but he also stresses that there are "international, Congressional, and executive sanctions," and the admin has the power over some but not all. Worth keeping in mind when thinking about this issue, and the potential for any deal that goes beyond the current one-page MOU. Iran will want sanctions relief, and the US govt may not be in a position to provide it to an extent Iran finds acceptable--not immediately, and possibly never.

Review conferences for the Nuclear Nonproliferation Treaty have failed to produce consensus outcome documents since 2010. Europeans should not let the principle of acting collectively to reduce nuclear threats become irrelevant, argues @JDMenton. carnegieendowment.org/europe…

Amid uncertainty caused by the Iran war, the global drive for nonproliferation has stalled. With Europe diplomatically marginalized, efforts to curb the spread of nuclear weapons risk becoming irrelevant, says @JDMenton. carnegieendowment.org/europe…

I love speaking to the next generation of up and coming leaders.
This week, we hosted nearly 100 young professionals and students for the 2026 Mort Abramowitz Junior Fellows conference. The full day of programming featured expert panels and breakout sessions on the most pressing issues in foreign policy today and how to build effective policy in a turbulent world. To cap off the day, we were joined by @margbrennan, moderator of @CBSNews's @FaceTheNation, for a keynote conversation moderated by Carnegie's @danbbaer. She offered reflections on her reporting career and lessons for young professionals interested in the intersection of foreign policy and media.

In a call with reporters just now, Adm. Brad Cooper of @CENTCOM says Iran has opened fire on U.S. warships and commercial vessels today, but declines to say whether the ceasefire between the U.S. and Iran is over. U.S. forces returned fire and destroyed some Iranian small boats.

“Tehran wagered that Washington had underestimated it, and that surviving the conflict would strengthen rather than weaken its hand.” @JDMenton and Mohammad Ayatollahi Tabaar unpacked why Iran may be able to quietly rebuild its nuclear program: carnegieendowment.org/emissa…

I'm looking forward to joining @dassen_lars and @RachelBronson1 for this timely conversation. Spoiler alert: operating nuclear power plants should NEVER be targeted for attacks.
Next Monday, April 13, the Bulletin will host a virtual panel on concerns around nuclear power plants becoming war targets, particularly in Iran and Ukraine, and the implications for the future of nuclear energy. Watch on our YouTube channel. ⬇️ youtube.com/live/CQGbJKEbzy8
