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.
A black and white map of the location of each flight of Minuteman III ICBMs (comprising 10 missiles each) based around F.E. Warren AFB in Cheyenne, Wyoming. Twenty flights (designated A through T) totaling 200 missiles are shown in southeastern Wyoming, northeastern Colorado, and southwestern Nebraska. Five of these flights (P, Q, R, S, and T, all in Wyoming) are no longer active, their missiles having been removed when 50 Peacekeeper ICBMs (which replaced an identical number of Minuteman IIIs beginning in 1986) were retired between 2003-05.

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...

New START’s expiry accelerates nuclear modernisation and vertical proliferation, undermining NPT credibility and threatening the global non-proliferation regime.

When the U.S. bombs a country it is negotiating with, other nations notice. Korbel Prof @debak.bsky.social explains why the strike on Iran doesn't just end one deal — it reshapes every future conversation about nuclear weapons. @us.theconversation.com

War on Iran during nuclear negotiations undermines the US’s ability to talk peace around the world − and the effects won’t end when Trump leaves office
Conducting military strikes against a nation that is engaged in negotiations to reduce its nuclear capacity has set a dangerous precedent.

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

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.

How is U.S.—China rivalry fueling a dangerous cascade of nuclear proliferation across Southern Asia? @debak.bsky.social explores the ripple effects of AUKUS and regional competition. 📖 Read here: tnsr.org/roundtable/n...
"Cascades of Competition: Southern Asia, the Indo-Pacific, and AUKUS" by Debak Das

Nuclear stability in Southern Asia is being shaped by different layers of competition in the Indo-Pacific. This article highlights two dynamics that are shaping nuclear competition in the region. The first, within Southern Asia, is states finding space to escalate at lower levels of conflict to address nuclear and 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 and China on the other. The second dynamic is a cascade of reactionary vertical proliferation that is occurring in the Indo-Pacific as a result of China and the United States’ strategic competition. While Washington and Beijing are responding to each other’s nuclear arsenals, India is responding to China’s arsenal, and 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.

I’m happy to share this paper in @cpsjournal.bsky.social on democracy and national narratives, with insights from South Korea and Taiwan. It is part of a special issue on postcolonial narratives with @paulschuler.bsky.social, @deandulay.bsky.social, + others. journals.sagepub.com/doi/full/10....
This paper explores how democratization can reconstitute understandings of nationhood by empowering a new class of “storytelling elites”---those with the institutional and rhetorical resources to challenge the state’s narrative. In this critical juncture, storytelling elites may challenge (1) the bottom-line premise or (2) the sideline elements of the prevailing national narrative. Their narrative strategies, in turn, shape how the terms of the debates are redefined and structured under democracy. I develop this argument through a comparison of “One Korea” and “One China” narratives in postwar South Korea and Taiwan. Using interpretive process tracing of archival and other qualitative data, I find that democracy helped entrench “One Korea” narratives in South Korea but displace “One China” narratives in Taiwan, as new storytelling elites challenged dominant narratives of “oneness” to varying degrees. This resulted in increasingly divergent support for unification as a national objective, with enduring implications for peace.

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.

Debak Das @debak.bsky.social · 16/09/2025
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).

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.

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.

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).”

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.”
