I join Michal Feldon, Ahmed Alfarra, Eyad Amawi, Barry Danino, Feroze Sidhwa, and Ruth Gibson to make the case for reopening the humanitarian corridor from Gaza to the West Bank for medical evacuations in @thelancet.com: www.thelancet.com/journals/lan...

It’s been a privilege to write with @eliavl.bsky.social in this effort to think through the normative underpinnings of IHL on the protection of objects: Making Sense of International Humanitarian Law's Protection of Objects papers.ssrn.com/sol3/papers....

The final version of my article on forcible reprisals (Yale Journal of Intl Law) is up. It discusses the theory behind the prohibition, highlights its normative core, and analyzes the Iranian/Israeli discourse on force which is also relevant to the current war. papers.ssrn.com/sol3/papers....

@justsecurity.org's Israel-Us-Iran collection has already developed into a mini-syllabus for the war's legal aspects. All of the pieces can be found here, and surely more will come: www.justsecurity.org/114556/colle...

The Trump Administration keeps throwing new arguments at the wall to see what might stick--but each one is worse than the last. This is an excellent piece by @eliavl.bsky.social explaining why Rubio's recent "double preemption" argument is a non-starter. www.justsecurity.org/133093/preem...

Prof. @eliavl.bsky.social explains how the @icrc.org Commentary on the Fourth Geneva Convention closes loopholes and reasserts international humanitarian law's core protective function. Part of our symposium with @ejiltalk.bsky.social & @icrclawpolicy.bsky.social www.justsecurity.org/131465/closi...

All this and more, a plug for my @justsecurity.org colleague @eliavl.bsky.social ‘s excellent book on Occupation in International Law (OUP 2022). Luckily he gave me an extra signed copy in recent weeks so encourage you all to get your own - you will find it useful in the week’s ahead.

Teaching a legal course this semester where recent armed conflict events are relevant, or know someone who is? The IHL Syllabus Supplement connects educators with salient law and policy discussions. Curated from JS archives by @bechamilton.bsky.social and Danae Askar.

My recommendations involve Yale Law School, Ali Khamenei, and Numenor

Seems pertinent

"the combat decisions he has made" Hegseth is setting up Admiral Bradley to take the blame for killing the survivors--which is just the tip of an immense iceberg of illegal acts. U.S. military officials beware: Following orders is not a defense to murder or war crimes.

Thanks so much. This has been an incredible honor.

Thanks!

Just uploaded an updated version of my forthcoming chapter for The Cambridge History of IL, discussing IHL in the post-Cold War era. The new version updates some issues and revisits the general framing of the period, which is profoundly different from today. papers.ssrn.com/sol3/papers....

4 pm Fri 14 November 2025 - Join us next week for the Award Ceremony for the Max Planck-Cambridge Prize for International Law (MaxCamPIL) 2025 which will be presented to Prof Eliav Lieblich. Further info: buff.ly/cr5MraV

I wrote an analysis of the US draft Security Council on Gaza. In short: it's rife with problems that must be resolved.

My analysis of some key issues in yesterday's ICJ Advisory Opinion is now online. I discuss the general context of the Opinion; central aspects in its findings on humanitarian duties; and the different approaches towards the duty to cooperate wrh the UN, as advanced by different judges.

One thing I can say about the ICJ opinion from yesterday: it cuts through the BS. Some muddled reasoning about the duty to cooperate because some judges disagreed on its scope. Also, an important declaration by Judge Cleveland. I hope to publish an analysis (very) soon.

1/ In case anybody missed it, the ICRC just published the new Commentary on the Fourth Geneva Conventions: ihl-databases.icrc.org/en/ihl-treat... This is an impressive project will surely dominate discussions in the field of protection of civilians under IHL for years to come.

So ... this is taking place next month at Cambridge. Receiving this prize is an incredible honor for me, and I'll be thrilled to meet in Cambridge those of you who are around and interested in attending! www.lcil.cam.ac.uk/max-planck-c... www.lcil.cam.ac.uk/press/events...

Officials say GHF aid sites being shut down, in accordance with Gaza deal https://www.timesofisrael.com/officials-say-ghf-aid-sites-being-shut-down-in-accordance-with-gaza-deal/

No words to describe this day

This is of course a "happy" day to the extent that things can be "happy" now. The key is what will be the mechanism that would prevent resumption of active hostilities after the hostages are returned. I personally have no faith (to say the least) in the actors involved. Let's hope for the best.

Stares into almost 20 years of Netanyahu

OUR BATHROOM MIRRORS ARE VITAL TO OUR NATIONAL SECURITY

Looking forward to @esil-sedi.bsky.social's annual conference, where I'll be chairing the Agora on the Laws of War. This is a dark time to discuss these issues, which is also why they are so important. I'm glad that our panel focuses on issues that are key to understanding this moment.

1/ I worked at DoD. I literally cannot imagine lawyers coming up with a legal basis for lethal strike of suspected Venezuelan drug boat. Hard to see how this would not be "murder" or war crime under international law that DoD considers applicable. Read expert analysis by @bcfinucane.bsky.social⤵️

I don't remember a darker moment

Earlier this week, we sent an urgent letter to Israeli authorities expressing grave concerns regarding the plan to expand the hostilities in Gaza, as reflected in statements by the Minister of Defense. The list of signatories reflects a broad consensus among local international law academics.

Last week, we sent the following grave warning to Prime Minister Netanyahu regarding the continuation and expansion of the war in Gaza.

2/ The Presidents' letter: "According to the considered judgments of prominent legal experts within Israel ... these proposals would constitute serious violations of international law, amounting to war crimes and crimes against humanity." Here's the apparent referent (Israeli scholars' letter)

1/ An inflection point The Presidents of five Israeli universities send letter to Prime Minister Netanyahu (more have joined the letter since) Calling on Netanyahu - to address hunger crisis in Gaza - to issue an "unequivocal condemnation" of recents statements by ministers

Sadly, my year at Cologne ends. It's been an amazing experience to visit the Cologne Center for International History and Law @chlcologne.bsky.social, and a privilege to inaugurate the Kelsen Visiting Professorship there. Anyone working on these subjects should follow this exciting new Center!

Since the start of the Gaza war, leading Israeli legal scholars have written numerous letters raising concerns over grave international law violations. We are publishing these letters for the first time in a collected English edition, with a summary by Kai Ambos. verfassungsblog.de/internationa...

1700 Israeli academics, including Nobel laureates, university presidents, provosts and deans send a clear message to Israeli government: do not pursue the population concentration plan in Gaza, as this is immoral, and would constitute a war crime and a crime against humanity.

Guess it’s time for Netanyahu to bomb someone

Thanks @timesofisrael.com for this detailed and in-depth report. www.timesofisrael.com/manifestly-i...

#ICJ judges must be perceived to embody impartiality. Roy Schondorf and Ava Drai argue that clearer ethical boundaries on perceived conflicts of interest must be developed to preserve the Court's continued authority and legitimacy. www.justsecurity.org/117167/judic...

Glad to see that @nytimes.com quoted our letter on the minister of defense's "plan" to push civilians in Gaza to a tent city in Rafah. There is still time to backtrack from this awful and illegal idea. www.nytimes.com/2025/07/14/w...

I am proud of my friends who wrote and signed this statement. Thank you!
