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.

Will the U.S. resume nuclear testing? Is "A House of Dynamite" plausible? Does missile defense work? If you're curious about nuclear policy, ask NTI's Paul Dean all your questions tomorrow at 1:00pm ET. us06web.zoom.us/meeting/regi...

"Reprocessing belongs to a bygone era—not today’s nuclear energy resurgence. It has failed on cost, failed on security, and failed to deliver real benefits. The future belongs those who pick proven technologies that can be deployed now and rapidly scaled," writes Ross Matzkin-Bridger. Read more. ⤵️

All countries remain dangerously unprepared for future pandemic threats. The world must work to prepare now, because the cost of inaction is far too high. www.vox.com/future-perfe...

@camanpour.bsky.social & @ernestmoniz.bsky.social (@nti.org) — head of the Nuclear Threat Initiative — discuss the film House of Dynamite and reveal how long a U.S. President would really have to respond to a nuclear attack Watch Christiane Amanpour Presents: The Ex Files 🗂️ on @globalplayer.com 🎧

The Asia-Pacific Leadership Network, a group of former senior diplomats and military leaders from the Asia-Pacific region has issued an important call opposing any resumption of nuclear explosive testing, a move that would undermine decades of global restraint and threaten international security. 🧵⤵️

🚨 APLN is deeply concerned about announcements to resume nuclear testing. This would end nearly 3 decades of global consensus against nuclear explosive testing + threaten the stability of our region & the world. Here's why it's dangerous 🧵 (1/7) www.apln.network/analysis/sta...

Our CEO, @ernestmoniz.bsky.social, spoke with @amanpourpod.bsky.social about President Trump's recent comments on nuclear testing. Hear what he had to say and watch the full episode here: www.youtube.com/watch?v=JEQq...

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.

Fun Fact: the United States tests nuclear delivery vehicles like missiles all the time. What no one has done this century, other than North Korea, is detonate a nuclear weapon.

To younger generations, nuclear threats often feel like a thing of the past. Engaging requires new tools, like art and film, to connect with people in ways they understand and humanize the issues. www.nti.org/risky-busine...

As nuclear security issues become more intricate due to tech advances, geopolitical rivalry, and new threats, dialogue among major powers is vital. The recent China-U.S. Track II Dialogue on Nuclear Security in Beijing, co-convened by NTI, brought together experts to discuss global nuclear security.

"Research shows narratives must connect with young people in a deeper way to have a lasting impact. A House of Dynamite creates a connection by not placing the blame on an individual or falling into good vs. evil tropes," writes NTI's Anusha Trivedi in our latest blog post.

"The only way to prevent another catastrophic nuclear detonation is to eliminate nuclear weapons from the face of the Earth. We can never be safe while living in a house made of dynamite," writes Hiroshima governor and president of Hiroshima Organization for Global Peace, Hidehiko Yuzaki.

Assuming that the missile in 'A House of Dynamite' carried a several-hundred-kiloton nuclear warhead and detonated directly above Chicago's Loop, what would follow? @patriciajaworek.bsky.social and Isabelle Williams of @nti.org explain. ⬇️

For 33 years, all U.S. presidents, including President Trump during his first term, preserved the moratorium on explosive nuclear testing because they understood testing would do more harm than good to U.S. national security. The same logic applies today: It is unnecessary, unwise, and unwelcome.

From the Suez Canal blockage to Covid-19, we’ve seen how fragile global economic systems can be. In an interconnected world, the economic ripple effects of nuclear weapons use would be catastrophic. NTI’s Patricia Jaworek, Isabelle Williams, and Page Stoutland researched these effects. Read more ⤵️
