President Trump's interview on 60 Minutes did very little to clarify his stance on the United States resuming full-scale nuclear tests for the first time in more than three decades. Let's look at some of his statements. 1/11

Resuming U.S. nuclear testing, as President Trump has suggested, “would do more to benefit our adversaries than the United States," says @coreyah.bsky.social on @npr.org. More from Corey on why: www.npr.org/2025/10/30/n...

Read @nicolegrajewski.bsky.social and @jdmenton.bsky.social piece, "MENA at the Threshold? Proliferation Risks and Great Power Competition", in a series of essays by @tnsr.org on the shifting global nuclear order. Check it out here: tnsr.org/roundtable/n...

In the fall, I wrote a piece for @carnegienpp.bsky.social about the hazards of playing political football with international oversight. Today, Iran's president announced the suspension of cooperation w/ the #IAEA. 🧵

Me in @carnegieendowment.org’s Diwan: The end of open hostilities has not brought clarity to Iran’s strategic direction. Instead, it has exposed an ongoing effort within the political and military establishment over how to interpret the war’s outcome. carnegieendowment.org/middle-east/...

“In the absence of cooperation, future crises will be hard to avoid and even harder to de-escalate.” @jdmenton.bsky.social on nuclear uncertainty – and the need for diplomacy – in Iran, for @foreignpolicy.com: foreignpolicy.com/2025/06/27/i...

Really great piece, and perspective, from @nktpnd.bsky.social

"In the days and weeks to come, policymakers will have to carefully distinguish between Iran’s legitimate frustrations and domestic political constraints and attempts to manipulate these conditions to mask clandestine proliferation ambitions."

In @foreignpolicy.com I wrote about Iran and why nuclear uncertainty is bad for regional stability. Unclear diplomatic priorities + backlash against the IAEA w/in Iran are setting us down a dangerous path. @carnegieendowment.org @carnegienpp.bsky.social foreignpolicy.com/2025/06/27/i...

Tired: JCPOA 2.0... Wired: KEDO 2.0

Some thoughts about Trump's comments today re further nuclear diplomacy with Iran + the Majlis bill to suspend Iran's cooperation with the IAEA (tldr: individually: bad, together: very bad!)

Per Rose's remarks, she's the opposite of Oz- what's behind the curtain is even better than what's on screen. Richly deserved award, and moving presentation.

IAEA Director General Grossi and @coreyah.bsky.social (my new boss!) take the stage at #nukecon.

At the Carnegie nonproliferation conference and IAEA chief Rafael M. Grossi spent a bit of time making the case for nuclear-propulsion in commercial shipping. Really interesting.

My colleague, @jdmenton.bsky.social, opens #nukecon.

Just announced: Iranian Foreign Minister Abbas Araghchi will deliver a keynote (virtually) at our Carnegie International Nuclear Policy Conference on Monday morning. carnegieendowment.org/events/2024/...

There are a few ways this could play out- some worse than others, but any further blow to oversight of Iran's nuclear program would ultimately yield minimal leverage... and huge risks. Working to restore what has been lost, and align M&V with Iran's current capabilities would be mutually beneficial.

🚨2 days left to register for the Carnegie International Nuclear Policy Conference!!🚨 Ft phenomenal speakers on nuclear energy, missile defense, US proliferation policy, Russian nuclear doctrine + more @carnegieendowment.org @carnegienpp.bsky.social carnegieendowment.org/events/2024/...

Excited to see this panel at Carnegie’s Nuclear Policy Conference - “Back to the Future? Nuclear Proliferation Risks in an Era of Uncertainty,” featuring the 3 co-chairs (and 1 member) of the NTI-CEIP-Belfer Task Force on Nuclear Proliferation and US Nat Sec. carnegieendowment.org/events/2024/...

DOGE cuts at the top U.S. nuclear security agency could enable threats to national security. @coreyah.bsky.social explained in @nytimes.com: www.nytimes.com/2025/03/17/u...

Trilateral statement from Russia, China, and Iran on the status of Iran’s nuclear program—a clear signal of their effort to preempt a response to potential snapback sanctions. 🧵

"The three countries stressed the necessity for all states to refrain from any action that undermine the technical, objective and impartial work of the IAEA"

@nktpnd.bsky.social very kindly had me on his @warontherocks.bsky.social podcast a few weeks ago to chat about Iran's nuclear program, and what we might see from Tehran, Washington, and the region in the coming months.

On Ankit Panda's very good nuke podcast Thinking the Unthinkable, he hosts his fellow Carnegie fellow Jane Darby Menton to discuss the Trump Redux era U.S. approach to Iran's nuclear program. @nktpnd.bsky.social @carnegieendowment.org @warontherocks.bsky.social warontherocks.com/episode/thin...

YPT is a phenomenal opportunity for students and young professionals to engage directly with high-level nuclear experts and practitioners from around the world. You don't want to miss this one (and for my fellow academics, please share with your students!) carnegieendowment.org/events/2024/...

Amid increasingly tense geopolitics, growing nuclear threats, and risks posed by rapidly evolving technologies, @BelferCenter & @CarnegieEndow & NTI have established a new high-level Task Force on Nuclear Proliferation and U.S. National Security.

#Nukesky if you’re a PhD student, postdoc, or junior faculty, apply to be a Stanton Fellow with the @carnegieendow.bsky.social’s Nuclear Policy Program. Applications are due on Dec 20. Happy to talk about it for those who are interested. carnegieendowment.applicantpro.com/jobs/3572279

@carnegieendow.bsky.social's nuke team is assembling! Be sure to follow the best team in the business: @jamiekwong.bsky.social, @tongzhao.bsky.social, @lrand11.bsky.social, @jdmenton.bsky.social, @nktpnd.bsky.social, @nicolegrajewski.bsky.social

Some of my colleagues from @carnegieendow.bsky.social’s Nuclear Policy Program are now on BlueSky: @jdmenton.bsky.social @jamiekwong.bsky.social @tongzhao.bsky.social @nktpnd.bsky.social

Iran still trying to thread the needle- deploying more advanced centrifuges (and gesturing to vague other options). Unclear if the (limited) measures reported yesterday re 60 percent stockpiles and inspector designations are already defunct.

Capping the stockpile of 60 percent enriched uranium is probably a signal, but it carries little substantive weight at this point. In expanding its nuclear program, Tehran has degraded some of the tools it uses to indicate diplomatic openings. diplomatic.substack.com/p/iran-agree...

Today, along with our partners at @belfercenter.bsky.social & NTI, Carnegie is pleased to announce a new high-level Task Force on Nuclear Proliferation and U.S. National Security. carnegieendowment.org/posts/2024/1...

Given today's reporting on Iran's nuclear program, reupping a piece I wrote for @carnegieendow.bsky.social on why weaponizing inspector access for leverage is a bad idea (and resolving outstanding issues would be in everyone's interest) carnegieendowment.org/research/202...

We are delighted to have launched the Risk Calculus @BerkeleyRisk--a new series that seeks to bring you some of the best and brightest working at the intersection of #technology, politics, and #security. In this series, we focus on the past, present, and future of #wargaming: Shall We Play a Game?

Event for Bay Area nuke folks!! We're hosting Mallory Stewart for a conversation about the future of nuclear arms control. RSVP here! www.eventbrite.com/e/the-future...

This WSJ article is dangerously wrong in asserting that some of the ships accompanying the aircraft carrier Gerald R. Ford “have nuclear capabilities.” US Navy surface vessels have not been armed with nuclear weapons since 1992, after President George H.W. Bush ordered their unilateral retirement.
