“President Trump himself has said that nuclear weapons are a bad idea. Why then is his administration requesting the equivalent of more than FOUR MANHATTAN PROJECTS this year for nuclear weapons?” Listen to Political Director @connormmurray.bsky.social's statement: www.youtube.com/live/W4ANf1w...

We're proud of our Council endorsees Derek Tran, John Garamendi and @gene4va.bsky.social who stood up and said NO to the excessive Pentagon topline during yesterday's HASC markup of the National Defense Authorization Act! Learn more about our house candidates: livableworld.org/meet-the-can...

@repgaramendi.bsky.social once again leads the charge on common sense nuclear policy changes during HASC NDAA markup. Great to hear @sarajacobs.house.gov support removing the arbitrary floor on deployed ICBMs! It’s important to ask “why” on nuclear weapons and more members should!

The @thebulletin.org experts were clear: the Doomsday Clock is a call to action. We all have a role to play here. Talk to your friends, colleagues and whoever will listen. The time for action is now. It is 85 seconds to midnight.

Thank you to @repbillfoster.bsky.social for organizing House floor speeches on the dangers of nuclear weapons and the need for arms control! Great to see so many @livableworld.bsky.social champions speaking out on these issues!

The U.S. maintains its nuclear arsenal using advanced simulations, continuous monitoring, and rigorous assessments—methods that provide more accurate insights than past explosive tests ever did, explains NTI’s Dimitri Kusnezov, former Chief Scientist at the National Nuclear Security Administration.

@jackieschneider.bsky.social: Keeping a human in the loop in nuclear decisions is such a resoundingly logical decision...but the devil is in the details... AI can mimic human behavior but it has significant bias, and that bias tends toward escalation. #CACNP2025

"Resilience by autonomy can become escalation by default" says Dr. Jesse Kirkpatrick at #CACNP2025 when discussing AI in nuclear command, control and communications. It's why we need to ensure there are guardrails and multiple authentication.

⏰STARTING SOON!!!⏰ Join our virtual annual conference -- Getting Off the Collision Course: The Case Against Arms Racing -- at 4:30 p.m. ET and share your thoughts as we go using the hashtag #CACNP2025! secure.everyaction.com/rhSOFnj8ekO4...

@mjgault.bsky.social: We have avoided nuclear war because we've been lucky, but also because we've been human... The real danger of nukes at the dawn of AI is that justified by efficiency in the name of modernization, AI will replace the next Stanislov Petrov

There are books, films, etc. that are meant to inform and there are ones meant to entertain/provoke thought. Don’t completely dismiss something clearly meant to entertain/start a conversation because you find the premise or details implausible. #AHouseofDynamite

Good reporting here from @nickturse.bsky.social - Trump has deployed 35,000 troops against his own people theintercept.com/2025/09/17/t...

This is great. We know servicemembers must be asking themselves whether this is really the mission they signed up for. Great to see some public pushback against the echo chamber.

The latest from @scientistsorg.bsky.social colleagues @mknight.bsky.social and @mattkorda.bsky.social... Another question I would pose: why are we unwilling to consider that a 1:1 replacement of current missiles is even strategically necessary given investments in other areas?

Don't forget that foundational investments in the #NNSA's nonproliferation capabilities mean we have off-the-shelf tools for out-of-the-ordinary situations. With at least 400 kgs of enriched uranium in the wind, what would a regime collapse mean for global security? 1/5

Don’t let them tell you these weapons are necessary, efficient, or making us safer! #NuclearWeapons #ArmsControl @livableworld.bsky.social @upinarms-us.bsky.social

Another awesome piece by colleagues at @scientistsorg.bsky.social! I wonder how many of my friends outside the #nuclearweapons space are aware that any U.S. president can single-handedly start a nuclear war whenever they want.

AI has a long way to go before it is a truly reliable source of information. This is especially true when it comes to #nuclearweapons. The example in the @thebulletin.org piece here is illuminating...

So this is … odd. Out of nowhere, the top US intelligence community official posts a three-and-a-half minute slickly-produced video across social media platforms on the dangers of nuclear war. What is the context? And why is this coming from the DNI and not the secretary of state, or the president?

Great work by the Nevadans Against Nuclear Weapons Testing coalition. State-level action can lead the way for federal officials and sends a clear sign that a return to nuclear weapons testing is unnecessary and harmful!

Here comes the Golden Boondoggle. It will cost upwards of $2 Trillion and not work. Almost every thing Trump and his military officials say in this story is simple not true. It will NOT protect America. But it will make contractors, like SpaceX, very rich. www.politico.com/news/2025/05...

Great work from my colleague, Shawn, on the tensions between India and Pakistan. We need responsible international engagement to keep the worst from happening. Reminder: both of these nations have nuclear weapons...#armscontrol #diplomacy

Actions speak louder than words. Trump is trying to paint himself as a peace president while his administration and pro-war Members of Congress continue to prioritize weapons over diplomacy.

Thrilled to have skilled colleagues, like Emma, at the Center and Council! Check out her latest piece.

Can’t say we didn’t tell people but bears reminding….

Tuning into the Heritage "Golden Dome" event so you don't have to. Things I'm listening for: - A clear grappling of the full cost - A contextualizing of the off-def balance - An integration of adversary counter-moves - Any amount of critical analysis on the "need" Will reply here if we get any

Great piece that includes quotes from @nukesofhazard.bsky.social's ED John Tierney on why "Golden Dome" is not only an expensive, but also a potentially dangerous endeavor. www.cnn.com/2025/03/22/p...

There is no shortage of things that I disagree with in the continuing resolution that the House passed yesterday (like sending $185m from nonproliferation to weapons). This one doesn’t even make sense/just seems punitive?

Great day spreading awareness about the dangers of nuclear war on Capitol Hill, including dropping a copy of “Nuclear War: A Scenario” off with Speaker Mike Johnson’s team. #educateDONTescalate

Tell your member of Congress: Support H.Res.168, the Opposing U.S. Military Action Against Mexico Resolution. We won’t stand by while Trump drags us into another disaster. www.congress.gov/bill/119th-c...

More important work from @nuclearwilson.bsky.social @lucasruiz4.bsky.social! However, I have seen nothing that tells me this administration has any plan to achieve this goal and so it remains typical bluster. I hope a plan emerges!

Same govt that is canceling subscriptions to certain news outlets for govt employees and banning others from the White House...the free speech guise is tenuous at best.

At what point are we going to start taking him by his word and do something about it?

Elon Musk with a chainsaw on stage, firing nuclear safety officials and employees working to counter bird flu (remember 🥚 price drama?), canceling programs that train and hire some of the smartest people into government (PMF etc.). I think a lot of people need to take a hard look at themselves....

Glad to see some in Congress publicly calling for continued strategic arms control. Good work by co-chairs of the Nuclear Weapons and Arms Control working group! www.reuters.com/world/us/dem...

Great job by our talented team and talented Emma!

I remain skeptical. Words are great but actions are better. I doubt champions for programs like SLCM will go down without a fight.

Whether DOGE ultimately gets this access or not….it is yet another example of how irresponsible it is to let unvetted people run through our government without a plan. Even the possibility of this should be worrying!

Congrats to @nukesofhazard.bsky.social alum @atomicbell.bsky.social, the new head of @thebulletin.org! thebulletin.org/2025/02/an-i... I agree that "all civil society organizations and governments will have to adjust and be ready to adapt to meet the challenges that we’re seeing today."

Great opportunity with fantastic colleagues.

Though symbolic, the trend line continues in the wrong direction.

Good new piece by my colleague, John Erath, for our @nukesofhazard.bsky.social blog: armscontrolcenter.org/putting-amer... There are opportunities for the new administration on the nuclear front. Let's hope they take them...

Some folks were so opposed to inclusion in the military during yesterday's hearing that they couldn't even stomach one more "I" in the word "military."

Chairman Wicker lists Sentinel as one of three top Pentagon programs facing issues. He calls Pete Hegseth nom "unconventional" and compares him to "unconventional" candidacy of Donald Trump. I'm not sure that's a ringing endorsement for many.

Will be very interesting to see if/when/how Congress manages to get the CR across the finish line. Seems as though there is plenty of dislike to go around: no money for victims of US nuclear legacy, lots of funding for "unrelated" policy, etc. Folks may be sticking around through the weekend.

Our latest on the compromise NDAA. Buckle up because the nukes are getting more funding.

Good step. Now let’s pass the language proposed in the annual defense bill to make this the law of the land in the U.S.

Had a pretty awesome conversation/discussion with some Catholic University of America students about nuclear weapons and ethics yesterday. Don’t let anyone tell you the younger generation doesn’t care about this issue. #nuclearweapons #nukebsky

Likely won’t completely abandon the other platform yet but may become more active here! We need more engagement on #nuclearweapons and today, we saw what that can look like when 9 Members of Congress spoke about the dangers of nuclear weapons on the House floor.

Agree with Stephen. It’s great to hear Members speak about this on the record. We need more of that!
