ELN Programme Head for Nuclear and Multilateral Disarmament, @olivermeier.bsky.social, spoke to @deutschewellerss.newsmast.social.ap.brid.gy about Iran's capacity to build a nuclear bomb under the JCPOA, versus today, and the potential for a new deal. www.dw.com/en/iran-us-w...

We are in a much worse place than in 2015 about preventing a nuclear-armed Iran, I told Deutsche Welle. "The attacks have not solved the problem. They have made it worse, because more people in Iran now believe a nuclear weapon is needed to deter future US attacks." www.dw.com/en/iran-us-w...

Continuing our P5 series on the 2026 NPT RevCon, Tianjiao Jiang sets out China's stance: Renewed P5 dialogue, greater clarity on nuclear modernisation, and collaborative approaches to proliferation, whilst highlighting opposition to extended deterrence. europeanleadershipnetwork.org/commentary/p...

The White House Military Office Marine Corps aide is on “Football” duty for Trump’s trip to MAGA Inc. events at Trump Winery, Charlottesville. The ~45-lb. satchel follows Trump 24/7, enabling him alone to authorize the use of any of our ~1,770 deployed nuclear weapons—up to 900 on alert—at any time.

You don’t say? “You know what’s a war crime? Having a nuclear weapon. Allowing a sick country with demented leadership to have a nuclear weapon. That’s a war crime.” — Donald J. Trump, April 6, 2026

France plans €36 billion boost to rearmament, nuclear deterrent expansion: "The ​draft law proposes an increase in number of nuclear warheads, whilst maintaining nuclear arms spending at about 13% of the overall ‌defence budget. France ⁠spends roughly €5.6 billion" annually on nukes. is.gd/QmOUBy

Russia’s foreign intelligence service (SVR) is again warning about nuclear threats. After claiming Ukraine is pursuing nuclear weapons, it now says the EU is too. Short thread 🧵

French MOD says they've kept the HEU and plutonium from the warheads dismantles after the Cold War and will use it for the increase of the nuclear arsenal recently announced by Macron. www.ledauphine.com/defense-guer...

Continuing our P5 series on the 2026 NPT RevCon, Sahil V. Shah examines the UK’s approach. He calls for less focus on big promises and to instead build on past achievements, maintain dialogue, and strengthen the institutions that enable progress. europeanleadershipnetwork.org/commentary/p...

I don't see how this can be interpreted as anything other than a threat to attack Iran with nuclear weapons.

What can go wrong? Missile with fragmentation warhead, deployed for the first time in combat, used on target next to sports hall and elementary school. www.nytimes.com/2026/03/29/w...

5. More irresponsible, populist and nationalist leaders of nuclear weapon states, with sole authority to use nukes. 6. Decision times over nuclear weapons use compressed as a result of new technologies in nuclear command and control. 7. Lower nuclear threshold because of "integrated deterrence".

Four weeks before 2026 #NPTRevCon is set to begin: "A lawmaker said a fast-tracked bill proposing Iran’s exit from the Nuclear Non-Proliferation Treaty and a shift in nuclear policy has been submitted to parliament’s legislative body." www.iranintl.com/en/202603281...

Secretary Jeremy Pocklington told MPs nuclear spending would continue to grow, Defence Nuclear Enterprise to account for “between about 20% and 25% of the MOD’s overall budget.” That growth reflects both inflation and broader expansion in nuclear portfolio. 🙄 ukdefencejournal.org.uk?p=67895Perma...

🎙️ Public Webinar: Iran one month on @theeln.bsky.social and @una-uk.bsky.social are pleased to announce a public webinar to discuss the evolving situation in #Iran one month into the war, and its implications for global security and international law.

Join us for this first @una-uk.bsky.social @theeln.bsky.social joint webinar to assess the implications of the U.S. and Israeli attacks on Iran for global security and international law.

I write about how 🇮🇳 & 🇵🇰 are incorporating AI into their militaries, increasing the need for credible "guardrails" to reduce escalation risks and recognize mutual vulnerabilities despite the politics of the region: www.apln.network/analysis/com... Thanks @kulkarnitanvi.bsky.social & @apln.network!

Tomorrow at the UN Press Association in Geneva, we will be launching the latest Nuclear Weapons Ban Monitor report. Here we explains what the report is about and stay tuned tomorrow to hear more. Read the previous reports here: banmonitor.org #NuclearBan

Russia has submitted its national report to the 2026 NPT Review Conference (currently only in Russian – link in the first comment). Much of it is as you would expect if you have been following recent developments, but there are some pretty significant changes. A thread 🧵 1/15

A new article in Contemporary Security Policy from CISAC fellow Anna Ferl & colleague Jana Baldus examines how apocalyptic imaginaries, exceptionalism and control, shape governance of AI and nuclear weapons, shifting focus toward risk management over disarmament. www.tandfonline.com/doi/full/10....

This is truly amazing. If you wanted to do this ridiculous thing, there was at least a way to avoid putting money directly into Iranian government hands. But, that would require thought, strategy, and diplomatic work. ofac.treasury.gov/media/935376...

This reads quite dangerous - according to @politico.com, Putin has proposed to Trump to stop intelligence sharing with Iran if the US stops intelligence sharing with Ukraine. According to the report, the US rejected this, but for the Europeans it is quite a poisonous idea:

And now for some good news (hopefully): "An international taskforce backed by US, Germany, Britain, Canada and France, among others, will track down all remaining elements of the program and destroy ​them under supervision of the Organisation for the Prohibition of Chemical Weapons." is.gd/ei4kzo

Iran burning all bridges.

Read this great piece by @carmenwunderlich.bsky.social on the dilemma's facing Germany ahead of #NPTRevCon: "Berlin must confront the growing gap between its self-image as a defender of multilateralism and an NPT bridge-builder and its actual policy choices."

So, Trump's Folly is sustaining the regime in Iran. Smart.

This 👇‼️ "Meloni, Merz and von der Leyen may believe they are being more realistic and pragmatic than their idealistic predecessors. The opposite is true. If Europe abdicates its commitment to democratic rules, norms and law, it simply ceases to exist as a collective entity."

Good explainer why we will always need impartial, reliable treaty-based transparency and verification arrangements, like under @ctbto.bsky.social or #OPCW: "Planet said it made decision “independently”, ... .

Good, balanced EU petition and open letter to "Support Spain’s Stand Against War with Iran". Read/sign here www.openpetition.eu/petition/onl...

If Iran is so completely beaten why would Trump need such help? Let's hope Europeans don't step into this trap.

I was just disinvited from the Air War College where I’d been asked to lecture on my book, which is a history of U.S. civil-military relations.

Our analysis suggests that Patriot interceptor-missile usage in the first three days of the Iran war may be comparable to that for the whole four years in Ukraine

As the Hormuz case shows, even reversible actions can wreak havoc on the global economy and are extremely hard to counter - a feature of deterrence, not a bug. Nuclear use would be far more devastating and irreversible. And, if miscalculations happen, not impossible 8/8

Fantastic and scary piece on why keeping a "human in the loop" does not even begin to address the many problems associated with the misuse of AI for military purposes.

Interesting Economist story from Shashank Joshi on the difficulty of sending in a team to deal with Iran's HEU -- with a brief quote from yours truly. www.economist.com/middle-east-...

Must-read piece by @tomdannatt.bsky.social @bechamilton.bsky.social in @justsecurity.org on illegality of Israeli and US attacks on Iran: 'It is difficult to see past conclusion that ... “tacit support given by many Western States” can, in essence, legitimate aggression.' wp.me/p5gGh3-yHT

This isn't really how Nuclear Posture Reviews work. Are we to completely disregard Biden's 2022 NPR and rely on an outdated eight-year-old document for authoritative guidance on US nuclear strategy?

New war reason just dropped.

German Vice Chancellor Lars Klingbeil today rejected Berlin’s participation in the escalating military conflict in Iran, describing the U.S.-Israeli campaign as “not our war” and flagging legal concerns over the strikes.

Unconditional surrender was the standards the US sought with Japan in WWII and led to the dropping of the only two nuclear weapons in the history of warfare . . . . and even then Japan was able to obtain conditions including the continuation of the Imperial line.
