1/n - China’s military parade as expected was an extreme display off military equipment. This included display of several new nuclear weapons systems, including some modified or entirely new. www.youtube.com/live/-aH6rGs... This thread includes preliminary descriptions; more later: 👇

📌 ICYMI, @nukestrat.bsky.social, @mattkorda.bsky.social, @mknight.bsky.social, and I just released a pretty cool report on the targeting strategies of nuclear-armed states. Check it out!

My latest in @postopinions.bsky.social - the 5th installment of our @scientistsorg.bsky.social series "The Next Nuclear Age" How a president might come to launch a nuclear strike Massive thanks to @sebphilippe.bsky.social for helping us model what a nuclear attack on DC might look like ⬇️⬇️

NEW REPORT from @nukestrat.bsky.social, @mattkorda.bsky.social, @elianajjohns.bsky.social, and @mknight.bsky.social, with generous support from @norskfolkehjelp.bsky.social 🔗 fas.org/publication/targeting-strategies-nuclear-armed-states/

🆕 Planning for the Unthinkable: the targeting strategies of nuclear-armed states Intense secrecy around nuclear targeting means that most individuals—including lawmakers—do not have much understanding of how fateful decisions about what to target during wartime are made.

Want to learn more about who controls one of the most powerful nuclear arsenals in the world??? Check out this excellent piece in @postopinions.bsky.social by my good friend and colleague, @mknight.bsky.social!

Amazing article by the amazing @mknight.bsky.social of @scientistsorg.bsky.social in today's WPost on the president's sole and unchecked authority to start a #nuclear war. Well worth your time. Well worth your action to oppose this dangerous policy. www.washingtonpost.com/opinions/int...

My latest: @projectsyndicate.bsky.social asked me (and four other analysts) to offer our thoughts on whether US allies should begin thinking about building their own nuclear weapons. My answer: as bad as things look now, proliferation can make things worse. www.project-syndicate.org/magazine/tru...

"To understand how it could all go wrong, it is useful to look at some examples of how it almost did." @nukestrat.bsky.social, @mattkorda.bsky.social, @elianajjohns.bsky.social and @alliemaloney.bsky.social of @scientistsorg.bsky.social have the latest: wapo.st/4jK0VjO

"If a nuclear war happens, it could very well start by accident." From @nukestrat.bsky.social, @mattkorda.bsky.social, @elianajjohns.bsky.social, and @alliemaloney.bsky.social in @postopinions.bsky.social "How Nuclear War Could Start" 🔗 below

"Humans are imperfect, so nuclear near-misses and accidents are a fact of life for as long as these weapons exist." @nukestrat.bsky.social, @mattkorda.bsky.social, @elianajjohns.bsky.social and @alliemaloney.bsky.social of @scientistsorg.bsky.social have the latest: wapo.st/4jK0VjO

The @postopinions.bsky.social released our 2nd article of the Next Nuclear Age. www.washingtonpost.com/opinions/int... @scientistsorg.bsky.social @nukestrat.bsky.social @mattkorda.bsky.social @elianajjohns.bsky.social @alliemaloney.bsky.social Everyone makes mistakes. Even w/ nukes.

"Today’s global nuclear landscape is far more complicated and, in many ways, more precarious." ✍️ Released today: the first @washingtonpost.com op-ed from @scientistsorg.bsky.social! Kudos all around on this momentous partnership exploring the next nuclear age. www.washingtonpost.com/opinions/int...

Nuclear weapons never went away. The world just ignored them for a few decades. We no longer have that luxury. Welcome to the Next Nuclear Age. Our first of a series with @washingtonpost.com @postopinions.bsky.social is out today. @scientistsorg.bsky.social www.washingtonpost.com/opinions/int...

Great new piece on the Trump admin's antilabor practices and recent slashing of the Federal Mediation and Conciliation Service by my fiancé @kjboyle.bsky.social

Wanna learn about our team at @scientistsorg.bsky.social's 2025 China nuclear forces estimates but you're more of a visual learner?? The team at @thebulletin.org put together an amazing video on YouTube that distills the topline info from our Notebook into 6 minutes 🤩

New find today: Assemblée Nationale parliamentary document regarding the 2025 finance bill states that France will deploy a new variant of its tête nucléaire océanique (TNO) nuclear warhead with the new M51.3 submarine-launched ballistic missile.

You can catch our nuclear triad (@mknight.bsky.social , @alliemaloney.bsky.social, and @elianajjohns.bsky.social) repping Team FAS at #NukeCon 🚀 Say hi!

I’m bummed illness prevents me from attending @carnegieendowment.org #NUKECON next two days. But if you’re going, make sure to check in with my colleagues @mknight.bsky.social @mattkorda.bsky.social @elianajjohns.bsky.social @jonatomic.bsky.social from the @scientistsorg.bsky.social nuke team! 👋

Public health policy should be public knowledge – elimination of the FOIA office at the CDC is an attack on the transparency owed to Americans about how their government functions. A disaster for researchers who work to keep our public health apparatuses honest.

Between 2006–2015, the United Kingdom repeatedly announced its intentions to decrease its nuclear weapons stockpile to <180 weapons. Fast forward to 2021, the UK flipped: it would extend its stockpile to 260 weapons. How did we get here? @elianajjohns.bsky.social explains fas.org/publication/...

"The modernization of China’s nuclear arsenal has both accelerated and expanded in recent years." How large is China's arsenal today? Find out in the latest Nuclear Notebook from @nukestrat.bsky.social, @mattkorda.bsky.social, @elianajjohns.bsky.social, and @mknight.bsky.social.

"Shocking" (not) news of the day: the US Air Force, after completely mismanaging a massive, unneeded effort to build high-priced, destabilizing, vulnerable land-based, nuclear-armed missiles, is looking to extend the life of the ones they already have until 2050: gulfnews.com/world/americ...

My latest piece on the budgetary and scheduling challenges facing the programs underpinning the UK's nuclear warhead sustainment and modernization & how the reduction in public transparency makes it increasingly difficult to understand and debate these challenges. fas.org/publication/...

I am extremely pleased to share this [email protected] report published today by me and @nukestrat.bsky.social on the return of the USAF nuclear mission to RAF Lakenheath. ⬇️ fas.org/publication/...

☢️ I've collected 800+ resources for those working on WMD issues in my "LearnWMD Spreadsheet" learnwmd.wixsite.com/learnwmd/the... Recently, I've gone through and updated all links & information. I've also broken out the OSINT resources into their own tab. Be sure to check it out!

🚨Applications for the FAS Open Source Nuclear Analysis Bootcamp are due by the end of the day on February 23rd! Don't forget to apply and share with your fellow nuke nerd friends 🤓 @scientistsorg.bsky.social fas.org/osint-bootca...

Air Force is suspending work on a significant part of new Sentinel ICBM program, ordering a pause on launch facilities under development. @bychrisgordon.bsky.social has the scoop. www.airandspaceforces.com/air-force-or... A result of rushed planning and poor oversight. fas.org/publication/...

🚨 Within the next 60 days (now much less), the Trump Administration will review OMB Guidance M-24-10 & M-24-18, which lay out how the federal government should use, acquire, and manage AI.

Air Force now says Minuteman III ICBM will be deployed until at least 2050. www.defensedaily.com/last-minutem... Five years ago it was 2036. And who can forget the warnings it’s falling apart, no margins, and extending would cost more than new Sentinel. 🙄 Background: fas.org/initiative/i...
