Ran @wellerstein.bsky.social ‘s NPT simulation in my nuclear weapons course this morning. Students loved it, and it went surprisingly well… until we got to the security assurances component.

I’m delighted to announce that I’ll soon be joining the University of Oslo as a PhD research fellow in political science. I’ll be studying strategic stability, emerging tech, and regional geopolitics with Arctic and East Asian case studies.
Excited to get back to sunny Norway 🇳🇴

It is interesting authors of the report say metallurgy was conducted in Building 1. It's my understanding that, historically, UF4 to metal production happens in Building 3.

Building 3 is directly next to Building 1, and has seen extensive roof corrosion over the years.
