A senior official in the Japanese government commented that Japan should possess nuclear weapons. It seems like a good time to post again my co-authored open access article with @doyoung-lee.bsky.social . www.tandfonline.com/doi/full/10..... Curious about the domestic and international reactions.

I didn't know the existence of Faroe Islands until this afternoon, but it was leading against Croatia until a few minutes ago, to qualify for men's football world cup. Where can I watch the game? The island has like 55000 people, and many of the team members are not professional football players.

I just had an email exchange with a high school student headed to @bsog.be next year about my recent article with @luissimonn.bsky.social www.tandfonline.com/doi/full/10..... She may have been being nice to her future academic advisor, but I'm still glad to see that open-access publications are

With Trump approving nuclear-powered (albeit not nuclear-armed) submarines for South Korea, this piece by @doyoung-lee.bsky.social seems even more relevant to policymakers. muse.jhu.edu/article/973856. Great that @tnsr.org is an open-access journal! I'm not sure if the path for ROK nuclear sub is

Who in North Korea are in their epistemic community on nuclear strategy? How did they learn nuclear strategy, and how do they update their thinking on the subject? Could they have academic/scientific exchange with American counterparts?

I read President Trump's executive order to guarantee security for Qatar: www.whitehouse.gov/presidential.... It looks significant, but is this an alliance? @bashleyleeds.bsky.social? Maybe I just haven't seen, but it seems to be a unilateral declaration and not signed by Qatar. Alliance agreements

Happy to have met a couple of alumni today. They seem to be doing very well. Their family must be proud, and I'm also proud to have played a small role in their education.

I came across this article about Rwanda and DRC www.wsj.com/world/africa..., and it reminded me of my article with @luissimonn.bsky.social on wedge strategies. doi.org/10.1080/1352.... I have no expertise on the region, but it seems to make sense for Rwanda to engage in internal wedging against DRC.

I have been pleasantly surprised by the state of Japan-South Korea relations lately. Of course, there are many landmines that someone can step on any time, but that is always the case. President Lee's shift in his stance toward Japan is important, but public opinion in both countries are also very

I enjoyed and learned much from Dr. Gideon Rose's talk at CSDS today. On the question of pushback from other actors, I wondered about the differences from the so-called soft-balancing during the George W. Bush administration. Different US policies, and different responses. Curious about both what is

US willingness clearly down: "as protégés come to doubt the ability or willingness of patrons to defend them, they are likely to shift away from loyalty and towards exit." Hedging in the form of nuclear armament will be an important topic in the coming years. www.tandfonline.com/doi/abs/10.1...
