How and why do nuclear delivery vehicles proliferate? I am delighted that my book, 𝐃𝐞𝐥𝐢𝐯𝐞𝐫𝐢𝐧𝐠 𝐭𝐡𝐞 𝐁𝐨𝐦𝐛: 𝐓𝐡𝐞 𝐒𝐩𝐫𝐞𝐚𝐝 𝐨𝐟 𝐍𝐮𝐜𝐥𝐞𝐚𝐫 𝐃𝐞𝐥𝐢𝐯𝐞𝐫𝐲 𝐒𝐲𝐬𝐭𝐞𝐦𝐬 𝐚𝐧𝐝 𝐭𝐡𝐞 𝐆𝐥𝐨𝐛𝐚𝐥 𝐍𝐨𝐧𝐩𝐫𝐨𝐥𝐢𝐟𝐞𝐫𝐚𝐭𝐢𝐨𝐧 𝐎𝐫𝐝𝐞𝐫 answering this question will be published by @cornellupress.bsky.social in 2027.

The most likely reason this AI answer is wrong is that it only considers the locations of the USAF bases where these operational ICBMs are deployed: F.E. Warren in Wyoming, Malmstrom in Montana, and Minot in North Dakota. But F.E. Warren’s missiles are spread across Wyoming, Colorado, and Nebraska.

What does the end of the New START treaty mean for the nuclear non-proliferation regime and the NPT? I'm glad to have this new piece out at Observer Research Foundation Middle East. Especially this week with the NPT Review Conference underway. orfme.org/expert-speak...

I'm looking forward to speaking at the Colorado Foothills World Affairs Council tomorrow on this new reality of a world without arms control treaties and how that might affect the future of nuclear proliferation. If you're in the Denver area, do come by! #Nuclear #ArmsControl

What happens when the last remaining nuclear arms control treaty expires? On Feb 5, the New Strategic Arms Reduction Treaty will end & the first time since the Cold War that the US and Russia would have no legally binding limits on their nuclear arsenals. Learn more from Korbel's @debak.bsky.social:

For the first time in 54 years, there won't be an arms control treaty between the U.S. & Russia next week. It was pleasure to discuss the impeding expiration of the New START Treaty with India's World Magazine. @josefkorbelschool.bsky.social @siecenter.bsky.social www.youtube.com/watch?v=t5YB...

In the list: Korbel's @epsteinprof.bsky.social & @debak.bsky.social explain that without credible U.S. security guarantees, nuclear proliferation is likely to increase rapidly across Europe and Asia. Link to article: foreignpolicy.com/2025/03/14/t...

As analysts debate what Trump’s statements on nuclear testing mean, we’ve rounded up some of our best coverage of how the current U.S. administration could reshape the global nuclear landscape.

In @defensenews.bsky.social about India's Rocket Forces. So far, there has been no public discussion about the conventional deep strike capability against Chinese strategic infrastructure,” Das said. “The problem with adopting such a doctrine is that China could do the same.” tinyurl.com/nzxzcv4y

A new roundtable by CISAC affiliate @laurensukin.bsky.social and Rohan Mukherjee examines the evolving global nuclear order, with several papers by former CISAC postdocs that show the interconnected nature of nuclear challenges and the vital role of domestic politics.

Our latest roundtable examines the rapidly evolving global nuclear order. From North Korea to NATO, China to Latin America, this collection of essays explores the domestic and international forces reshaping nuclear security. Full roundtable: tnsr.org/roundtable/n...

Within Southern Asia, states are seeking space to escalate at lower levels of conflict to address nuclear & military asymmetry. Pakistan is seeking to create space to escalate at lower levels of conflict against India, while India is doing the same against Pakistan on one side & China on the other.

While Washington & Beijing are responding to each other’s nuclear arsenals, India is responding to China’s arsenal, & Pakistan is responding to India’s nuclear modernization. The technology transfers and submarine proliferation in the Indo-Pacific precipitated by AUKUS are intensifying this dynamic.

One year unilateral adherence to New START treaty being proposed by Moscow is a positive sign that the last remaining arms control mechanism between the US and Russia does not need to disappear after February 2026. #ArmsControl #NukeSky nbcnews.com/world/russia...

Confirming these assessments in 1979, Satish Dhawan, chairman of the Indian Space Research Organisation, told the Indian Parliament consultative committee that the Space Launch Vehicle, SLV-3, could, after some modifications, be used as an Intermediate Range Ballistic Missile (IRBM).

Ultimately, the Space Launch Vehicle-3 was successfully launched in July 1980. A few years later, the first stage of the solid fuel SLV-3 became the first stage of the nuclear-capable Agni IRBM that is today in India's nuclear forces.

India collaborated with France on space technology through the 1970s. French MoD discussed France's space technology for a potential Indian nuclear delivery system in April 1976. It concluded that the bilateral cooperation in space concerned both civilian and military domains.

In 1978, France concluded that all indicators in India’s space program—building laboratories for solid and liquid fuels, acquiring the license for the Viking engine, and India’s cooperation in the Ariane program—could be interpreted as a strong signal to acquire nuclear weapons.

The U.S. tried to stop India. Daniel Moynihan, US ambassador to India, said to Secretary of State Henry Kissinger that Washington should get India to privately agree “to go very slow in testing. Nothing more for a year or two. No weapons. Rocketry restraint. No missile system.”

Meanwhile, even within the Indian government, it was suspected that INSAT (Satellite program) for TV was “the public rationale for the nation pursuing an ambitious space programme, particularly the development of very large rockets…broadly equivalent to inter-continental ballistic missiles (ICBM).”

Korbel Prof @debak.bsky.social: Given the recent crises over China’s new ICBM silos, Iran’s ballistic missile testing, and North Korea’s continued expansion of missile forces, policymakers need to understand how states proliferate nuclear delivery vehicles to be able to limit their spread.
