“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...

@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.

“National leaders … must take the lead in finding a path away from the brink,” writes the Science and Security Board in the 2026 Doomsday Clock statement. “Citizens must insist they do so.” Watch the announcement: buff.ly/BGu0Zse

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.

How the U.S. Maintains Its Nuclear Arsenal—Without Explosive Testing

The U.S. ended explosive nuclear testing in the 1990s, but that does not mean we are unprepared. In its place, the U.S. uses a science-based program that checks the health of the stockpile…

@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.

@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

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

Trump Troop Deployment in U.S. Climbs to 35,000 Boots on the Ground

A federal judge found the deployment to LA violated bedrock constitutional law, but Trump’s domestic military campaign continues.

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.

Win Without War@winwithoutwar.bsky.social · last yr.

Today, we’re expanding our NotWhatYouSignedUpFor.org campaign — which connects service members to resources for responding to unlawful and immoral orders — to two major active duty military installations: Fort Bragg and Camp Lejeune.

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?

Mackenzie Knight-Boyle@mknight.bsky.social · last yr.

🚀In our latest @scientistsorg.bsky.social report, @mattkorda.bsky.social & I spill all things Sentinel: ✅ How did we get here? 📈 Why does the cost keep rising? 🤷‍♀️ Where's the program at now? 🕳️ What's up with the new silo situation?? Read here ⬇️⬇️

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.

The spread of hearsay about nuclear or other strategic weapons tests is not new—but novel digital technologies have added a new layer of complexity to the grapevine. "When Grok is wrong: The risks of AI chatbots spreading misinformation in a crisis," by @kjolvegeland.bsky.social.

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...

Trump to announce $25B funding for Golden Dome project

The price tag matches the amount in the president’s “big, beautiful bill” that lawmakers have yet to approve.

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

“The shrinking space for maneuver between India and Pakistan makes timely outside engagement all the more consequential,” writes Research Analyst Shawn Rostker in The National Interest. nationalinterest.org/blog/silk-ro... #NukeSky

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.

"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...

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

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?

A quick 🧵: The news of Congress potentially blowing a $1.1 billion hole in D.C.'s budget has certainly riled up a lot of people. But it's part of a larger trend of how Congress's years-long budget dysfunctions have bled into D.C.'s municipal government.

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
