We have long said that an accident anywhere is an accident everywhere. I also think an accident anytime is an accident for all time. We can (and I would say must) get nuclear energy right to address the climate crisis but we have to learn from the past. carnegieendowment.org/emissa…

Nearly 40 years since the worst nuclear disaster in history, @HigginbothamA, @mbudjeryn, @CoreyAH, and @michaelcrowley explore Chernobyl’s enduring legacy.
Ukraine's Ambassador to the U.S. @StefanishynaO will deliver opening remarks.

Also, noting: when next you hear someone say "oh, if only the negotiators on the JCPOA had tried harder, we could've gotten Iran to give up its nuclear program," this whole episode is a useful demonstration of why that assumption is wrong.
This isn't just me being snotty. 1/6
Happening soon! Register to watch online (or attend in person) at 0900 this morning.

On Nov. 21 @1PM EST, I will join Nevada's @repdinatitus and fmr. NNSA deputy administrator @CoreyAH for a briefing on Trump's threat to resume nuclear testing, the growing opposition to such a move, and options for a more constructive test ban policy. RSVP ow.ly/W05Y50XroEO

I don't regard a U.S. nuclear test as a done deal yet--it'd be a BIG mistake--but Trump's interview with O'Donnell certainly points in that direction. He doubles down on the Truth Social post.
Here's an excerpt, though I suggest reading the whole thing. Link in next post. (1/n)
China's also testing nuclear delivery vehicles. Spoiler alert: so does the US, including a planned Sentinel ICBM flight test in 2026. When POTUS said on 60 Minutes, "I'm saying that we're going to test nuclear weapons like other countries do." This would indicate status quo. 8/13
It is true that we might not know, and this uncertainty is serious. The State Department has raised these questions in the past. state.gov/adherence-to-and-c… 12/13
President Trump's interview on 60 Minutes did very little to clarify his stance on the United States resuming full-scale nuclear tests for the first time in more than three decades. Let's look at some of his statements. 1/13
Trump also said, "Other countries are testing. We're the only country that doesn't test" Well, it depends what he means by testing, and this interview did little to clear up the confusion. Russia last week "tested" two new nuclear delivery vehicles (nytimes.com/2025/10/29/world…) 7/13
More includes the PULSE facility at Nevada where we combine nuclear material and high explosives to study nuclear weapons performance WITHOUT creating a chain reaction, consistent with our int'l commitments. youtube.com/watch?v=Lz0SVeTX… 6/13
...the fastest measured supercomputer in the world, the DAHRT and Z machines, and more. lanl.gov/science-engineering… 5/13
But the main reason is because we have invested billions of dollars in tools and experimental facilities to understand how nuclear weapons work. These facilities include the National Ignition Facility (youtube.com/watch?v=6Eh2rZAD…) ... 4/13
Why is that? Because we have the data from more than 1000 nuclear tests (for comparison, USSR/Russia did 715, China <50, North Korea has done 6). armscontrol.org/factsheets/n… 3/13
