New New START or New Finish? 13.11.2022 29:33
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 th...

Another Crazy Train 22.10.2022 26:48
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. Jeffrey and Aaron take a knife to b...
The Janky Triad 18.10.2022 20:07
Does North Korea have a triad? Perhaps a boostrapped, janky triad? How mature is their arsenal at this point? North Korea lobbed a Hwasong-12 over Japan after a week of smaller missile tests, and sparked a testy exchange of missile tests and aircraft scramblings. Jeffrey and Aaron talk about missile overflights, what it means to begrudgingly accept a new nuclear power, and what North Korean nuclea...
Stealing the Zaporizhzhia Nuclear Power Plant 29.08.2022 26:14
What the heck is going on with the Zaporizhzhia Nuclear Power Planet? Aaron and Jeffrey walk through the safety situation, the open source assessments of what is going on, and what appears to be a Russian strategy to....steal a power plant?

Rules for Testing a Nuke 29.08.2022 31:15
Why isn't North Korea testing nukes? What are the signals and signs that precede a test? Jeffrey and Aaron talk testing indicators, the logistics of detonating a nuclear device in North Korea, and the proper use of the Chatham House Rule... The team talks about the impact of Michael Krepon on the field and on us personally. He will be greatly missed, and his importance and mentorship in the field...
The Last Days of the JCPOA 24.07.2022 32:14
As the President visited various states in the Middle East, Jeffrey and Aaron sat down to eulogize the JCPOA renegotiation attempts as they slowly slide farther off the rails. Iran's programs continue and it looks like the U.S. is preparing to continue into the sanctions and containment realm, as Israel continues its seemingly ineffective hardware sabotage campaign. The North Korea-ification of Ir...
The Wizards of Armageddon 01.07.2022 42:11
Jeffrey and Aaron walk through a piece of foundational field canon, The Wizards of Armageddon by Fred Kaplan, discussing its coverage of institutional and personal decisionmaking, picking apart the concepts of deterrence and compellence, and discussing the seemingly crystalized debate on the same core tenets, decades after the initial events.

Waiting for the Boom 04.06.2022 23:14
After a brief hiatus due to Jeffrey's house catching on a lil' bit of fire, the Arms Control Wonk team is back to take a look at North Korea's triple missile launch and looming possible nuclear test. Jeffrey and Aaron discuss the North Korean nuclear testing schedule, the expectations of precision that open source intelligence has generated, and what it means when half of the attendees at a nucle...
American ASAT Controls 02.05.2022 30:43
The U.S. has unilaterally committed to not conducting destructive anti-satellite missile tests! Jeffrey and Aaron walk through what the U.S. has actually normatively committed to, what this means for potential future attempts at arms control in space, and some of the institutional hurdles the U.S. must overcome for a long-lasting commitment to space-based arms control.

Carrier Killer: China's Anti-Ship Ballistic Missiles and Theater of Operations in the early 21st Century 16.04.2022 34:51
Gerry Doyle and Blake Herzinger join Jeffrey to talk about their new book: Carrier Killer: China's Anti-Ship Ballistic Missiles and Theater of Operations in the early 21st Century. The group sits down to talk through China's DF-21D and DF-26 missiles. Do they work? What do they do? What can they actually accomplish? How do navies adapt to the new threat environment? The group talks through the re...
Test Three Missiles... 24.03.2022 37:15
...get a pod. North Korea has conducted three (and, as I'm typing this, apparently four ), ICBM (or ICBM element) tests, with two labelled as "satellite" system tests. Jeffrey and Scott talk through an OSINT Oreo: Good OSINT to identify ICBM tests, BAD OSINT claiming that some agricultural fields were missile support areas, and then more good OSINT in the form of Jeffrey's talented class of mis...
The Bunga Bunga Theory of Deterrence 15.03.2022 45:17
Should we be worried that Russia may intentionally use nuclear weapons in Ukraine? Jeffrey and Aaron discuss the role nuclear weapons, conspiracy theories, and misinformation play within conventional wars and escalation dynamics. Aaron posits the Bunga Bunga Theory of Deterrence, wherein an individual actor's rationality can be gauged by the company they keep. Support us over at Patreon.com/ac...
Deterrence in Ukraine 24.02.2022 30:55
Russia has invaded Ukraine, and some folks are arguing that Ukraine could've deterred Russia "if it had never given up nuclear weapons." But they never "had" nuclear weapons. Jeffrey and Aaron talk through the control of nuclear weapons in Ukraine during the Cold War, and the "return" of those weapons to Russia after the fall of the Soviet Union.

Nuclear Security for Who? 15.02.2022 24:08
Jasmine Owens, Lead Organizer and Policy Coordinator at the Physicians for Social Responsibility, joins Jeffrey to discuss social justice and nuclear weapons. Jasmine and Jeffrey attack the tough issues facing culture within the nuclear security field, embedded bias, and the disproportionate impact these weapons have on minority and oppressed communities.

Networked Nonproliferation with Michal Onderco 08.02.2022 28:15
Dr. Michal Onderco, Associate Professor of International Relations in the Department of Public Administration and Sociology at Erasmus University Rotterdam, joins Jeffrey to talk about his new book, Networked Nonproliferation: Making the NPT Permanent. Dr. Onderco and Jeffrey talk about the history of the NPT extension, interpersonal relationships in diplomacy, and the methods and study of diplom...
Gimme Shelter 25.01.2022 23:30
After North Korea tested its new MaRV twice, a bunch of weird news stories suddenly started breaking about U.S. responses. Flights were grounded in parts of the West Coast, there was a shelter in place order up at the missile defense site in Alaska, and it seemed like someone may have mistook the North Korean test for an ICBM launch. Jeffrey and Aaron talk about the U.S. early warning and ballisti...
North Korea's MaRV 08.01.2022 25:35
North Korea tested what appears to be a maneuverable reentry vehicle (MaRV), which could support a tactical nuclear mission and subvert ballistic missile defenses. Jeffrey and Aaron talk through the difference between a MaRV and a hypersonic glide vehicle, discuss the development of the DPRK missile industry, and walk through North Korea's tactical nuclear ambitions. Other Episodes of Interest: G...
North Korea's Small SLBM 27.10.2021 29:22
North Korea seems to be taking its new, small, solid propellant missiles to the sea, after taking them to the show. Perennial friend of the pod and aficionado of all things submarine Joseph Dempsey of the International Institute of Strategic Studies returns to talk to Jeffrey about what it is that the DPRK tested this time, whether it is the same missile that the DPRK showed off at its recent mili...
A Fractional Orbital Bombardment System with a Hypersonic Glide Vehicle?? 19.10.2021 49:28
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 abou...
Glide or Die 07.10.2021 32:41
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 tes...
All Aboard the Missile Train 18.09.2021 38:51
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...
Not Lackin' LACMs 15.09.2021 33:26
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 mis...
Boiling Fish at Yongbyon 09.09.2021 32:45
Looks like Yongbyon is running a little hot. The IAEA has announced that it believes the DPRK is conducting a plutonium reprocessing campaign at Yongbyon. Jeffrey and Aaron discuss why the DPRK would want to do this. What could the mystery be? Why would the DPRK reprocess plutonium? For nukes. It's for nukes. Basically like the DPRK has been saying.

It's Always Cloudy in Novaya Zemlya 03.09.2021 25:35
Jeffrey and his team fear no cloud. Working with Capella Space to acquire cloud-piercing synthetic aperture radar (SAR) data, the MIIS team has been monitoring eternally-cloudy Novaya Zemlya, Russia, for evidence of Burevestnik nuclear-powered cruise missile tests. Evidence pointed to the Burevestnik test site being revived after the previous failures, and the team started utilizing radar return...
