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…

Genuine career highlight for me + lots of fun to join @ezraklein for a long conversation on Chinese AI policy & what that means for upcoming 🇺🇸-🇨🇳 talks. We recorded this last Thursday so **if** anything happened after that we might not have covered it... nytimes.com/2026/09/15/opini…

Excellent breakdown by @JDMenton on the US-Saudi nuclear agreement. Congress should make good use of the 90-day review period to satisfy themselves on the significant ambiguities and to attach legislation to shore up weaknesses.

After a dramatic rollout, Saudi Arabia and the U.S. are finally on the verge of a civil nuclear cooperation agreement. But what does the deal entail? And what does it leave behind? @JDMenton explains: carnegieendowment.org/emissa…

The text of the U.S.-Saudi nuclear cooperation agreement is out... that it doesn't meet the nonpro "gold standard" isn't news. The real question is whether the case for it holds up, or if if this deal is gilded rather than golden.

As I wrote for @CarnegieEndow the Saudi 123 tries to set its own standard, but the public text is notably vague on some key issues (e.g. alleged exclusivity commitments, the full scope of bilateral safeguards, what exactly was agreed re enrichment).

Some thoughts with @AndrewMLeber about the U.S. Saudi civil nuclear cooperation agreement, which was a long time coming, and now seems to be in flux by the hour.

Resounding silence from Saudi media outlets and most commentators since Trump’s latest post about the nuclear deal.

President Trump has formally approved a landmark agreement with Saudi Arabia that will provide the country with a civilian nuclear program and potentially open the door to uranium enrichment in the kingdom’s territory, according to U.S. officials. on.wsj.com/3RaoTge

Would like to bring back this memo style pls
The declassified 1962 memo for the UK prime minister informing him (in shakespearean prose) that the US accidentally fried Britain's Ariel satellite with its Starfish Prime high-altitude nuclear test.

And so the World Cup final will be between two teams who couldn’t beat Cape Verde in 90 minutes.

And which sites will they be allowed to visit? Also, is this a one-off? Or full restoration of Iran’s compliance with its Comprehensive Safeguards Agreement? The answers matter for determining whether this is show or substance.
Immediately or as part of a final agreement?

Will they? Lessons all seemed clear before the President launched this disastrous war, save for those happy to roll the dice with others’ lives and money nytimes.com/2026/06/17/us/po…

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…
