Wasted Opportunities with the JCPOA 27.08.2021 26:35
Bad news abounds for Iranian and US returns to JCPOA compliance. Aaron and Jeffrey talk through the frustration around breakout time requirements, the timidity of the Biden administration, and the shortfalls of the wait-and-see approach. Links of Note: The Economist article on OSINT, including Arms Control Wonk and the Slack channel, which is filled with only the most brilliant and beautiful of...
A SECOND SILO FIELD 13.08.2021 41:15
Matt Korda and Hans Kristensen with the Federation of American Scientists have tracked down what appears to be a second field of missile silos near Hami, Xinjiang. Aaron, Jeffrey, and Scott gather up to discuss the rapidly increasing number of missile silos, what this means for the shell game theory, how many missiles and warheads could be in the PLARF's ICBM arsenal, and how China strategically...
I Sing of Arms and the Man 28.07.2021 30:47
American weapons systems need better names. Tom Karako, Director of the Missile Defense Project at the Center for Strategic and International Studies, joins Jeffrey to talk about just what it is that inspires soldiers: Legendary, heroic, and historical names, not descriptive acronyms and jargon. What, are ALCM and JASSM not as sexy as Hades or Pluton? Tom explains his philosophical and classical b...
Nuclear Silos in the Chinese Desert 30.06.2021 34:21
Decker Eveleth and Jeffrey Lewis's team at CNS have found 119 silos for ICBMs out in the deserts of China. That's the largest expansion of PRC silos in history, by far, but it isn't totally clear what is going on, and whether each of these Bouncy Castles of Death represents a new missile or if there are some decoys in the mix... Aaron and Jeffrey discuss how Decker found these silos out in the mid...
The Space Launch Simorgh-asbord 24.06.2021 35:16
Jeffrey's team is at it again. This time, they (and Jonathan McDowell!) caught an unannounced (and failed) Iranian space launch attempt and have now caught what appears to be a second unannounced (and failed) Iranian space launch attempt. The failed launch detection was covered by Zachary Cohen and Oren Liebermann at CNN, who were kind enough to get the Pentagon to confirm that the first launch...
The Relevance of the Nuclear Posture Review 23.06.2021 39:40
Is the Nuclear Posture Review something worth doing, or a massive waste of time and political capital? Jeffrey and Aaron vote "waste." The NPR takes up a ton of time, leaves policy on autopilot during its duration, and burns a ton of bandwidth that could be used for actual reflection and policy change. But what is more valuable? No Review at all? An Integrated Deterrence Review? The team walks th...
Hyperbolic Hyper Hype 29.05.2021 30:15
The hype is real. Maybe it's a branding thing, maybe people forget ballistic missiles are a thing, maybe nobody thinks "glider force" sounds cool. But whatever the reason, people keep calling hypersonic glide vehicles fast compared to existing missile systems. Jeffrey and Aaron discuss hypersonic weapons, what people keep getting wrong about them, and why the D5 missile is so dang cool. Support us...
Israeli Rocket Motor Test 06.05.2021 17:48
On April 20, an Israeli twitter user posted a video of a large smoky cloud to his Twitter account with the comment "A mysterious explosion in northern Israel." Jeffrey and his team tracked down the "mysterious explosion," identifying it as a solid rocket motor test for an unknown missile or space system. Aaron and Jeffrey walk through the team's methodology, how they found the site, how they ident...
A Tale of Two Launches 01.04.2021 43:27
North Korea has been active the past few weeks, launching a set of cruise missiles (probably just coastal defense systems) and a separate set of ballistic missiles (which look like stretched KN23 short-range ballistic missiles) a few days later. But these events were received very differently by the Biden administration and analysts. Jeffrey, Aaron, and Scott discuss why these events were receive...
Making the Easy Stuff Hard: Re-joining the JCPOA 11.03.2021 31:54
Biden campaigned on rejoining the JCPOA, but some of that enthusiasm has dried up since he took office. Aaron and Jeffrey debate what's going on, strategies for negotiating re-joining the JCPOA, and the fallacy of letting the perfect get in the way of the good as people begin to advocate for "waiting for a better deal" again. Also, it is a good time to start listening to Season Two of The Deal , a...
New START and the Future of Arms Control 26.02.2021 33:21
President Biden has extended New START for five more years. But what are we going to do with those years? How to we actually advance stability? Aaron and Jeffrey talk about the steps necessary to secure stable, effective arms control treaties, the history of arms control, and the importance of tacking missile defenses alongside offensive systems.

Iran's New Space Launcher: Zoljanah 18.02.2021 30:16
Iran unveiled a new (mostly) solid-propellant space launcher, the Zoljanah! But it looks....different than the other space launchers. Besides having a new fuel type, the Zoljanah may not have many IRGC or military fingerprints on it, indicating that the Iranian solid-propellant programs are robust and expansive. Jeffrey and Aaron talk Iranian space programs, civilian vs. military control of resear...
Unravelling the Israeli Ballistic Missile Program 05.02.2021 39:46
Israel maintains a technologically advanced but understudied ballistic missile arsenal. Jeffrey and Aaron dive into the French, South African, and American influences on the arsenal, how to model the Jericho missile families, and the history of the Israeli ballistic missile program.

North Korea's Next Nukes 25.01.2021 42:45
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 syst...
Fancy Ass SWERVE 12.01.2021 53:02
On Thursday, Dec. 12, 2019, at 8:30 a.m. Pacific Time, the U.S. Air Force, in partnership with the Strategic Capabilities Office, conducted a flight test of a prototype conventionally-configured ground-launched ballistic missile from Vandenberg Air Force Base, California. But just what the heck did the DOD actually test? Jeffrey and team turn their analytic methods towards figuring out exactly wh...
The Donald and The Nuclear 7: Parting Shots 08.01.2021 23:58
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. Previous Entr...
North Korea's Biggest ICBM Yet 06.01.2021 47:54
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. For our episode on the October 2020 Military Parade in North Korea, click he...
New Year, New START, New Facilities in Iran 29.12.2020 39:05
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. Head over to the Arms Control Wonk slack channel to voice...
Dennis Gormley 02.12.2020 31:50
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 22.10.2020 42:24
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 decl...
Saving the World with Datayo 09.10.2020 44:34
Melissa Hanham , director of Datayo and Deputy Director of the Open Nuclear Network , joins Jeffrey and Scott to talk about Datayo, a project aimed at reducing nuclear risks and fostering a transparent, collaborative, and high-quality analytic information environment. Scott fawns over Datayo's video annotation capabilities for military hardware tracking, and Melissa talks about how much bandwidth...
The Deal 09.10.2020 32:43
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 fel...
At The Brink 29.09.2020 42:59
How do we step back from the brink and reduce the very real threat that nuclear weapons continue to pose? Nuclear weapons continue to impact people's lives, even if they are sometimes treated as historical threats of a prior era. Jeffrey and Aaron sit down with Lisa Perry and Dr. William Perry , 19th Secretary of Defense, to discuss their work conducting interviews with and chronicling the persona...
The Deal Episode 1: The Revelation 08.09.2020 29:07
In 2002, Corey Hinderstein, a young research analyst, follows a hunch after a routine press conference in Washington, D.C. The results of her scavenger hunt sparked a diplomatic crisis that stretched more than a decade, lasted through two presidencies, and ended with a deal that, depending on whom you ask, either "makes our country, and the world, safer and more secure" or is "a horrible deal that...
The Deal: Promo 07.09.2020 2:21
The Deal: 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. You can find The Deal on Apple Podcasts or your preferred podcast plat...
