The Pope and the Catholic Church have been extremely clear that we should build a world without nuclear weapons. This is something Trump himself has also said on repeated occasions, despite the lack of any actual action to achieve it.
Hot take: effective diplomacy requires trained professionals and patience.
We are capable of great things.
Next Monday, April 13, the Bulletin will host a virtual panel on growing concerns around nuclear power plants becoming targets in war, particularly in Iran and Ukraine, and the implications for the future of nuclear energy.

What has President Trump achieved with the war in Iran?
"The United States may have taken away some of Iran's nuclear capabilities—though crucially not its stockpile of highly enriched uranium and nascent bomb-making ability," writes Richard Nephew @richardmnephew.bsky.social.
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.
Join us for a discussion on the current situation in Iran this Monday at 3:15 pm CT/ 4:15 pm ET.

Excellent analysis from Matt Bunn.
Note the danger he cites that Iran still has a supply of 60% enriched uranium and deeply buried centrifuges that could spin it to bomb grade. This strike may have accelerated Iran’s efforts to get a bomb. What would Israel or the US do? Attack it?
🚨 JUST IN: Israel and the US strike Iran. It is a tragedy of Tehran's own making
Iran's strategy worked. Only up to a point, Nicole Grajewski (@nicolegrajewski.bsky.social) writes in @thebulletin.org.

The world faces a destabilising nuclear arms race as the New Strategic Arms Reduction Treaty (New START) between the United States of America and the Russian Federation expires on 5 February.
ELDERS’ STATEMENT | The Elders urge USA, Russia to halt nuclear arms race as New START expires
Putin and Trump must act urgently to secure a new deal, reduce nuclear risks and protect humanity.

“The Doomsday Clock is a sign of leaders’ failure to act responsibly in the face of existential threats. “They have not heeded the warnings of previous years, so once again the hands of the clock have moved even closer to midnight.” Juan Manuel Santos Chair of The Elders
“The looming expiration of the New START treaty between Russia and the USA means nuclear risks are likely to get even higher. This is intolerable. Humanity deserves better. Global citizens need to mobilise and make their voices heard, so leaders feel real and urgent pressure to change course.” Juan Manuel Santos Chair of The Elders
The Doomsday Clock has moved four seconds closer to midnight.
This is the consequence of world leaders’ lack of attention to the nuclear threat.

"The Doomsday Clock's message cannot be clearer. Catastrophic risks are on the rise, cooperation is on the decline, and we are running out of time. Change is both necessary and possible, but the global community must demand swift action from their leaders." — Alexandra Bell Bulletin President and CEO
“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.”

It is like a knife in my heart when I see what these thugs are doing to decent and loving people. He was trying to help a woman who had been violently pushed to the ground. And paid for that with his life, murdered by violent and vicious criminals masquerading as law-enforcement.
We're one year in. The speed, scope and severity of what's happening to American science is beyond anything we've seen before. The reliability of the Federal science and technology enterprise and the people within it, has been shattered. www.nature.com/articles/d41...

I had a really fun time working on the code that was used to make these fallout visualizations for this USA Today article. I will soon be incorporating some of it into the NUKEMAP and probably making a version of this "mass attack fallout mapper" for public use. www.usatoday.com/graphics/int...
In less than a month, the US and Russia will have no legally binding measures constraining each other's strategic nuclear arsenals. 60 years of work to prevent nuclear war between Washington and Moscow is being effectively abandoned. My take on what to do next: thebulletin.org/premium/2025...
People have a right to know about global threats. That's why the Bulletin exists. But we need your help.
At the Bulletin, we believe everyone has a right to know about global threats—because they endanger us all.

It is hard to overstate how wildly inappropriate it is to replace a National Climate Assessment--A process normally involving hundreds scientists, significant public and expert input, and US government-wide coordination--with five climate skeptics using AI.
