JL-3, You know me.

Thu, 16 Jul 2026 15:33:00 +0000

China has conducted a test of its JL-3 submarine-launched ballistic missile into the open ocean — a departure from its usual practice of lobbing missiles into the desert or splashing them down in domestic waters. Jeffrey and Aaron Stein sit down to talk about why China would test this way: what an open-ocean flight test actually demonstrates, how it mirrors the way the United States, Russia, France, and other nuclear powers have long tested their sea-based deterrents, and what it tells us that China is increasingly behaving like a normal nuclear weapons state. They also dig into what the test suggests about China's internal politics — who benefits from testing in a more conventional way, and what it means when the world's most opaque nuclear program starts doing things everyone can see.

MOU 404

Tue, 30 Jun 2026 23:16:00 +0000

The US-Iran MOU is humiliating, it was signed at Versailles, and its still not on any government website. In fact, if you try a .gov keyword search for Iran's commitment to not build nuclear weapons, the top result is Obama's 2015 Joint Comprehensive Plan of Action.

Aaron and Jeffrey work through why Trump was right to quit while he was behind, why continuing the fight wouldn't have changed a single comma, and why, weeks later, you still can't find the thing on state.gov.

The New START treaty has expired leaving the US and Russia without a bilateral limit on offensive strategic arms for the first time in decades. There is reportedly a handshake deal not to do anything drastic for six months while the two sides talk about the outlines of a future deal, but there seems to be little agreement about what such a deal might look like.

A Pod of Dynamite

Jeffrey and Scott watched the new Kathryn Bigelow movie "House of Dynamite" and they both have opinions.

The crew talks through both the artistic choices as well as the wonky details. "House of Dynamite" is an interesting take on missile defense and decisionmaking that doesn't quite commit enough to any philosophical or strategic camp, but ultimately may be the lens through which a lot of non-wonks view or interact with missile defenses, conceptually, as we move towards a potential major expansion of US missile defenses.

A Return to Nuclear Testing

Mon, 03 Nov 2025 14:44:00 +0000

Donald Trump directed "the Department of War to start testing our
Nuclear Weapons on an equal basis" with other countries. The
Department of War doesn't test nuclear weapons, the Department of
Energy does all the time in lots of different ways. Some people
worried this meant a return to explosive testing, others seemed to
think it was about delivery systems. Subsequent statements by the
Vice President and the Secretary of Defense didn't clarify things.

The Reason We're all Still Here

Sat, 14 Oct 2023 21:07:00 +0000

Take a listen to the latest season of Jeffrey Lewis's podcast, The Reason We're All Still Here

Far too often, governments behave like toddlers. They're fickle. They don't like to share. And good luck getting them to pay attention to any problem that isn't directly in front of them. They like to push each other to the brink, and often do. But when they don't, it's usually because other people enter the proverbial room. Private citizens who step up and play peacemaker when their governments won't or can't. People who strive for collaboration and understanding, and sometimes end up finding it in unlikely places. Those people and the work they do, they're the reason we're all still here.

This season, we'll hear from scientists, analysts, and idealists who have gone to crazy lengths just for a shot at making peace and building understanding From smoke-filled rooms in North Korea to secret labs in the Soviet Union… to the lawless seas, and even to the depths of outer space (or, at least, the conference rooms where they talk about the depths of outer space). This podcast tells the stories about the people holding us back from the brink.

Hosted by Dr. Jeffrey Lewis, a professor and scholar at the Middlebury Institute of International Studies on the Nonproliferation and Terrorism Studies faculty. Previously, he served as Director of the Nuclear Strategy and Nonproliferation Initiative at the New America Foundation and Executive Director of the Managing the Atom Project at the Belfer Center for Science and International Affairs at Harvard University. He is the founder of ArmsControlWonk.com, a leading resource on disarmament, arms control and nonproliferation issues.

New New START or New Finish?

Sun, 13 Nov 2022 13:53:00 +0000

The Biden administration has been working to re-kindle New START talks with Russia, while working to deter Russian WMD use in Ukraine, in an era that increasingly appears to be about risk management instead of risk reduction. How do you restart heavily managed talks in an era of COVID restrictions? How do you do on-site inspections during a conventional conflict?

Jeffrey and Aaron talk through the rough state of international nuclear arms control, the increasingly-complex balance of nuclear forces globally, and the core aspects of what makes deterrence actually work.

Another Crazy Train

Sat, 22 Oct 2022 21:54:00 +0000

The Russian invasion of Ukraine is giving people brain worms. Multiple terrible reports, citing oSiNt aNaLyStS, have recently been released and grossly overexaggerated the risk of nuclear weapons use around Ukraine. These reports, particularly about the "nuclear weapons convoy headed towards Ukraine," don't help anyone and just add noise to a chaotic narrative.

A Fractional Orbital Bombardment System with a Hypersonic Glide Vehicle??

Tue, 19 Oct 2021 00:42:55 +0000

This is a complicated one. According to Demetri Sevastopulo at the Financial Times, China tested something that sounds a whole lot like FOBS with an HGV. Something that orbited the globe and dropped a hypersonic glide vehicle against a target.

Jeffrey, Aaron, and Scott try to figure out what actually was tested (HGV-FOBS? An intercontinental glider? A super-lofted ballistic missile??), talk about what it means to be a "fractional orbital bombardment system" versus a regular ballistic missile, and why the pursuit of perfect missile defenses may make us all less secure.

Glide or Die

Glide or die, baby.

The North Koreans, on a real cavalcade of missile debuts reminiscent of 2017, have tested what they claim to be a hypersonic glide vehicle (HGV). Which means they are just checking off their list of goals, leaving a nuclear powered submarine, a MIRV, and a solid propellant ICBM as the main untested-but-announced capabilities....

While it isn't 100% clear that they actually tested an HGV, the team dissects what it might have been, if a DPRK HGV is realistic, and why HGVs and other missile-defense-defeating technologies fit the DPRK's national strategy perfectly.

Oh, and FOBS makes an appearance, almost entirely to give Scott nightmares.

All Aboard the Missile Train

Put another pot of coffee on because it is launch week again. North Korean launched two missiles off of the back of a train this week, right as the president of South Korea watched their own tests of a submarine launched ballistic missile, stealthy air launched cruise missile, ballistic missile test, supersonic anti ship cruise missile test, large diameter solid motor test, and good lord it is a hard week to keep up. Oh right and North Korea is expanding its uranium enrichment facilities.

One day we'll catch up to AUKUS.

Jeffrey and Scott try to keep up and parse through everything that is happening, from why trains are a strategically sensical choice for North Korean missile basing to why the South Korean conventional SLBM makes us very, very nervous.

Not Lackin' LACMs

Wed, 15 Sep 2021 20:53:49 +0000

The DPRK tested a cruise missile, but this time it was a big one. Like "INF Treaty" big, if that term still meant anything.

The DPRK announced that it launched a 1500 km range cruise missile, after months of hints that a strategic nuclear-capable cruise missile was in the works. While it technically does not fall under the United Nations Security Council resolutions sanctioning DPRK ballistic missile and space tests, it is a huge concern, especially since it is probably meant to carry a nuclear payload one day.

Jeffrey and Aaron talk about the tech, cruise missile proliferation, how the DPRK has been signaling this capability for a while, and why this is a very serious capability that needs to be addressed.

North Korea's Next Nukes

North Korea put on *another* parade, during the 8th Congress of the Workers' Party of Korea.

Kim Jong Un dropped some fascinating details about what the DPRK has allegedly completed, and what they may be working on, including a possible nuclear submarine and intermediate-range cruise missile. Then, he paraded some new missile hardware, including a new solid-fuel SLBM and some new short range systems.

And, to top it off, Jeffrey and Dave Schmerler found that the SLBM-test platform in Nampho harbor has been moved for a possible refurb, meaning SLBM tests may be possible in the near future.

Jeffrey and Scott try to parse out what the North Koreans have built, what they showed us at the parade, and what is to come this year.

Nancy Pelosi has indicated that Mark Milley, Chairman of the Joint Chiefs of Staff, has assured her that there are safeguards against an "unstable president" accessing "the launch codes" and launching a nuclear strike.

Jeffrey and Aaron discuss why that is wrong (and/or illegal), what the actual launch process is, and what the political strategy behind Nancy Pelosi's message may be.

North Korea's Biggest ICBM Yet

Wed, 06 Jan 2021 02:12:40 +0000

Jeffrey and crew have been busy at work modelling the giant ICBM that the DPRK paraded in October 2020, as well as tracing out its possible industrial provenance.

Aaron and Jeffrey talk through modelling methodologies, North Korean industrial espionage, and how to build robust public policies to account for uncertainty.

At the end of this awful year, Jeffrey and Aaron talk about the future of arms control, the future of analytics, and the future of the pod. 2021 will have a lot going on: New START expiration or extension, new facilities in Iran, figuring out what the heck the North Koreans are doing, what's going on with anti-satellite missiles, and more.

Dennis Gormley

Wed, 02 Dec 2020 01:50:55 +0000

Jeffrey and Aaron share stories about the life of Dennis Gormley, renowned proliferation scholar and celebrated professor. Dennis's work on cruise missile proliferation, tacit knowledge, and industrial expertise was foundational to the field of proliferation studies, and he was a caring, dedicated educator.

Dennis was a good friend and mentor, and is greatly missed.

The 2020 North Korean Military Parade

Thu, 22 Oct 2020 00:39:05 +0000

On 10/10/2020, the 75th Anniversary of the Founding of the Worker's Party of Korea, the DPRK showed of a lot of missiles. Again. In addition to all the stuff they've been testing over the last two years, they introduced a new, oddly shaped solid-propellent missile, the Pukguksong-4, and what appears to be the largest TEL-based liquid propellant ICBM in history.

Kim Jong Un gave the clearest declaration of DPRK nuclear policy to date.

Jeffrey, Anne, and Scott sit down for Anne's last official episode and talk about what we saw, what that it means for North Korea's nuclear posture, and what the DPRK's nuclear policy and strategy actually is.

The Deal

Fri, 09 Oct 2020 00:25:51 +0000

Now that a few episodes have dropped, Anne and Jeffrey talk about Jeffrey's new project, The Deal.

Jeffrey chronicles how researchers like Corey Hinderstein chased down data before satellite imagery was so easily available, Wendy Sherman's incredible memory for names, and just how many BBs Jeffrey has in his car.

The Deal tells the story of the Iran nuclear deal: how it came together, how it fell apart, and what that means for the rest of us. Hosted by Dr. Jeffrey Lewis, director of the East Asia Nonproliferation Program at the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies at Monterey. He tweets @armscontrolwonk.
