Arms Control Wonk

Jeffrey and his team have been OSINT'ing the heck out of the deployment of the Typhon Strategic Mid-Range Fires (SMRF) ((Typhon Smurf?)) to the Philippines, and tracked down the airport and deployment zone.

Recently the U.S. Army deployed the new Typhon SMRF system to the Philippines as part of an exercise, raising the ire of both the Russian and Chinese governments. The Army seemed to try and keep it relatively low profile initially but the Philippines just....tweeted it out basically. 

As the Pacific continues to bristle with missiles, Jeffrey and Aaron talk about regional escalation dynamics, who is buying what missiles, and who they are (or aren't?) actually pointed at...

Tom Schelling described escalation as a "curved slope" where you won't be able to predict when the final drop occurs, and Ukraine targeting an early warning radar in Russia certainly is at least a few steps down that slop.

Jeffrey and Aaron sit down at the intersection of "legitimate conventional military target" and "direct cause of nuclear escalation" to talk about the risks and justifications for bringing EW systems into a conflict, and discuss James Acton's idea of modern entanglement, and the connection between modern conventional and nuclear operations.

We have data! Jeffrey and Aaron walk through the new primary source data to figure out if either Iran's missile raid or Israeli's missile defense efforts were effective. This appears to be the first time that successful wartime ballistic missile defense intercepts can be validated via open source means, which is a major step forward for open source missile and BMD analysis. 

Jeffrey and Aaron also talk about the relative impact of conventional ballistic missiles, and what secondary effects must be considered when assessing the value of interceptors vs. offensive missiles.

And you may find yourself not complying with the IAEA

And you may find yourself in a war in another part of the world

And you may find yourself making a metaphor about an automobile

And you may find yourself enriching your uranium stocks, and building reactors

And you may ask yourself "Well, how did I get here?" 


Letting the days go by, politics will hold you down 

Letting the days go by, heavy water underground 

Into Fordow again, maybe to Isfahan

Once in a lifetime, realignment all around


Same as it ever was, Same as it ever was


Jeffrey and Aaron go through the current state of play in Iranian politics (just prior to its massive missile strike on Israel), particularly around the nuclear program and what the bomb genuinely means for security and Iranian internal politics, and review how we got here over the past 20 years of Arms Control Wonkery.

Road trip to Vegas.

As part of an NGO transparency visit, NNSA opened up the Nevada Test Site to a group of international nuclear weapons experts, including one Dr. Jeffrey Lewis.

Jeffrey goes through what he saw: P Tunnel, The BEEF, and the crown jewel, U1a. This was an NNSA exercise in transparency, aimed at showing the community and world that the U.S. stockpile stewardship and treaty verification exercises are separate from nuclear explosive tests. It was also, and we cannot underline this enough, extremely cool.

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, a leading resource on disarmament, arms control and nonproliferation issues.

Looks like everyone is preparing for a party. 

Between Russia's potential un-signing of a nuclear test treaty, threats to test "if the United States does," and refurbishments at Novaya Zemlya, things aren't looking great for the longevity of nuclear test ban norms. China and the U.S. have been modernizing too, though the U.S. has offered to allow monitors on-site to verify U.S. lack of testing. 


Jeffrey and Aaron sit down to talk about the recent developments in Russia, and the likelyhood that there will be a return to explosive nuclear testing in the future.

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 responds to U.S. ballistic missile defenses.

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 background, and the inspiration for his article in War on the Rocks about giving U.S. weapons systems respectable names more befitting of their purpose.

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 middle of the desert, whether each silo has its own missile or if this is a Shell Game with empty silos and decoys, and how this is going to impact arms control incentives in the very near future.

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 did, in fact, fail. We're still waiting to hear about that second one though...

Jeffrey and Scott walk through Iran's textbook space launch preparations, how Jeffrey's team tracked the preparation and launch, and how one assesses that a rocket flight failed in absence of a big, obvious explosion.

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 through the pitfalls of the NPR, propose some modest alternatives, and outline a possible alternative mission for the Missile Defense Agency....

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  received so differently, what the deal is with North Korea's newest short-range ballistic missile system, and what the Biden administration may be getting itself into with its denuclearization policy.

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.
