The ending of A House of Dynamite leaves many questions unanswered, intentionally. In reality, we won’t have that luxury. My colleague Isabelle Williams and I pick up where the movie ends, exploring what would unfold in the minutes, hours, and months after the missile hits Chicago.

1/n - Trump says something about nuclear weapons tests...It’s hard to know what he means. As usual, he’s unclear, all over the map, and wrong. 1. The United States has more Nuclear Weapons than any other country. Wrong. Russia has more nuclear weapons than the United States.

Great to see the UN Scientific Panel on Nuclear War Effects is now officially established and has appointed 21 members! The diversity of backgrounds reflects that this is a critical opportunity to reexamine the full range of effects in today’s interconnected world: press.un.org/en/2025/dc39...

There are claims out there that Ukraine’s attack on Russian strategic bombers (see article below) was possible due to provisions in the strategic nuclear arms control agreement New START which purportedly requires both parties to park their heavy bombers in the open. This is utter nonsense. 1/ 🧵

Russia issued a new nuclear policy document. Here is an illustration of the changes between the 2020 and 2024 texts relating to the conditions under which Russia might use nuclear weapons. I think its old wine in a new bottle.

we're hiring. come be the voice of NTI and have fun doing it. www.nti.org/job-listing/...

Preventing nuclear use must remain a top priority for leaders❗️Both NWS and NNWS have a role to play. I hope that neither side underestimates the other’s tolerance for risk & the danger of incremental escalation.

The new nuclear "Basic Principles" just dropped (h/t @dvsteff.bsky.social). The key change is that it's the aggression that "poses critical threat to the sovereignty and/or territorial integrity" instead of "puts the very existence of the state in jeopardy" publication.pravo.gov.ru/document/000...

“5 billion people could die from famine and hunger after a nuclear war between the US and Russia.”

My former @NTI_WMD colleague Ananya Malhotra and I wrote a paper on the global effects of nuclear conflict and their implications for nuclear policy, exploring how findings of nuclear winter were first received in the 80s, and what has or hasn’t changed 👇 #NukeSky www.nti.org/news/nti-rel...

Russia assured CTBTO Executive Director RobFloyd that it "will continue to fully participate in the work being done for the Treaty’s entry into force." t.me/ViennaMissio...

@elenachernenko.bsky.social reports that draft law on de-ratification of the CTBT by Russia has been published. The State Duma will consider it in three readings next week. The bill was signed by 440 deputies out of 450 — a record in the history of the State Duma t.co/U4RNQEF3m4

The CTBT de-ratification note - "The adoption of this law does not imply the termination or suspension of the CTBT ... It will allow the withdrawal of the ratification letter... Russia will continue to remain a participant of the Treaty with all the rights and obligations arising from it."
