- Reposted by Giovanni Mantilla1/ Important read from my friends Charlie Trumbull & @mikeschmitt.bsky.social Bottom line: A sentence you could easily miss in the Trump DOJ/OLC's Maduro memo concludes a new category of *civilians* can be lawfully killed during armed conflict. It is wrong. www.justsecurity.org/130603/olc-m...

- Finally out! www.tandfonline.com/doi/full/10.... Longer post to come but for now, key take-aways: international pressure matters, domestic pressure matters, international treaty law (however contested) matters, and super importantly these days, civil servants who believe in international law matter!

- With military options reportedly off the table, NATO and the United States are now discussing the creation of sovereign US bases in Greenland. MARKUS GEHRING & NASIA HADJIGEORGIOU explain why such sovereignty carve-outs would violate international law. verfassungsblog.de/why-us-sover...

- Struggling to redesign my small-group MPhil seminar "norms of humanity" amid so many breathtaking events. It's primarily historical, using IR approaches to int'l legal norms of HR, armed conflict, IHL. Any tips, texts, or class activities for incorporating discussion of our unprecedented present? 🙏

- Reposted by Giovanni Mantillayou don't need to add caveats agreeing that the head of state abducted is a bad guy before opposing abduction of a head of state by military force. If the rule was any head of government is fair game then the entire world would be a series of decapitation strikes and show trials in foreign courts.

- Reposted by Giovanni MantillaThe New York Times quickly sending out Douthat to argue that Mamdani’s victory doesn’t really matter is so predictable it borders on self-parody. Remember, folks: Every time the Right wins an election, it’s an undeniable expression of the will of the people. If a lefty wins, it’s just a blip.

- Upon the public announcement of one embarrassing British international legal position today, here’s another, historical (1964) one I just retrieved from the UK national archives. So-when did the position change, re UNSC resolutions’ binding character? Or am I missing some lawyerly nuance?
