I had a chance to talk about this piece in @foreignaffairs.com and the moral and political implications of claims that the war against Iran would liberate the Iranian people on @dwnews (link in comment)

Americans see local consent for U.S. military intervention as not only a “practical concern” but also as a “matter of moral principle,” writes @janinadill.bsky.social.

The list of countries threatened with U.S. military intervention is growing · Venezuela 🇻🇪 · Iran 🇮🇷 · Cuba 🇨🇺 · Greenland 🇬🇱 · Canada 🇨🇦 …just this year! Do they all want "Liberation"? No, I argue in @foreignaffairs.com

Ich hatte für die Sendung @ARD Monitor die Möglichkeit 🇮🇱s Vorgehen im 🇱🇧 & die 🇩🇪 Reaktion einzuordnen. Mir war wichtig drei Punkte hervorzuheben: 1) Die weitreichende Zerstörung von zivilen Objekten und Vertreibung der Zivilbevölkerung im Südlibanon sind mit dem internationalen Recht unvereinbar.

Is it possible to legally evaluate US targeting in the air war against Iran, 28 February-8 April? In this discussion I defended why a preliminary legal analysis is possible & necessary and address 4 types of targets struck by the US (& Israel) in Iran that raise distinct legal questions:

It was an honor to speak to Democratic Members of the US Congress about Israel’s approach to International Law in the West Bank. I used my time to make three points 1) We can be unusually confident in the conclusion that Israel’s conduct in the West Bank violates international law.

I agree with @monicahakimi.bsky.social 75% of the time. The 25% is when I learn the most. Thanks @craigxmartin.bsky.social for inviting me back onto the JIB/JAB Podcast and for leading this discussion on the attacks against Iran and implications for international law.

Eine Stellungnahme mit deutschen Kollegen in Rechts- und Politikwissenschaften zu der fehlgeleiteten deutschen Außenpolitik im Kontext des völkerrechtswidrigen Angriffs auf den Iran.

American Presidents invariably claim that the use of U.S. military force abroad benefits the local population. U.S. Presidents often explicitly or implicitly claim that "the intervened population" therefore welcomes U.S. military intervention - a powerful moral claim.

When the US or Israel blatantly violate int law for their own gain we mustn't mistake it for an effort to reform an imperfect system of laws. Thanks @tomdannenbaum.bsky.social & @bechamilton.bsky.social for saying this with clarity and integrity. justsecurity.org/133417/aggre...

The NYT Investigative team (and other news outlets) have reported in detail on the attack against the Elementary School in Minab, Iran. I had the opportunity to comment, but the law is not the story so there is more to be said. Allow me to elaborate:

Excellent explainer with analysis from @janinadill.bsky.social, @oonahathaway.bsky.social, @adhaque.bsky.social, Ben Saul, and Marko Milanovic: www.middleeasteye.net/explainers/u...

British PM Starmer says that U.K. bases will only be used for ’defensive’ operations and not ‘offensive’ ops. But how can that be so when they are being used by the aggressor? Great discussion here with Milanovic, @adhaque.bsky.social @janinadill.bsky.social www.middleeasteye.net/explainers/u...

📣 Reminder: Join us on 12 March (16–18h) at the Paulinum, Leipzig, for our panel “Peace and Security in Times of Hybrid Threats.” 🗣️Panel: Dr. Astrid Irrgang (ZIF) Prof. Dr. @janinadill.bsky.social (ECLAC) Oberst i.G. Katharina Benford (BAKS) Ulrich Hörning, Mayor of Leipzig German and English!

The UK's legal position on the use of its bases in the Middle East is solid with one glaring hole: The US cannot act in collective self-defence with the Gulf States. It is the aggressor. Ergo the UK cannot assist the US in collective self-defence.

Rousing speeches on European assertiveness & middle powers countering hard power do not a viable foreign policy make, it turns out. European, EU & Canadian responses to the US/Israeli aggression against Iran are short-sighted and help weaken the legal rules these countries depend on.

I had the opportunity to speak to the House Foreign Affairs Committee about the illegal US intervention in Venezuela. The UK must decide between "leading on international law" and "the special relationship", if the latter is a reflexive support of now legally unconstrained US Foreign Policy.

3 years into the war, Ukrainians' resistance territorial concessions has weakened slightly (compared to 07/2022 when we first ran this experiment), but they STILL categorically resist Russian control. New paper with @marniehowlett.bsky.social & @carlmc.bsky.social academic.oup.com/jpr/advance-...

I mean sure, but you know who else helped? Germany. Germany's behaviour during the 2-year long carnage in Gaza also helped. You cannot pick and choose. International law is not a menu. You have to respect it. Always. Otherwise it breaks down and then we're where we are now. #IntLaw #Germany

I wrote an Expert Comment for the University of Oxford on the implications of the US aggression against Venezuela for International Law and Global Security. My argument in brief below: www.ox.ac.uk/news/2026-01...

Some thoughts on DW News about what US actions in Venezuela mean for int. law & global security. Every state that cannot on its own stand up militarily to the US has an interest in not weakening the prohibition on invasion & head of state immunity. www.youtube.com/watch?v=VbvP...

I fear we are going to have to say this a lot again: Int law prohibits bombing countries for the sake of democracy. FOR VERY GOOD REASON. It tends not to work. Attacking a country because its leader lacks legitimacy - whether as pretext or sincerely held rationale - is still just an aggression.

“the principles of international law” rather prohibit bombing countries because their leaders “lack legitimacy”.

„Was fehlt, ist eine schlagkräftige Stellungnahme der ARD-Oberen an prominenter Stelle, ein von einer breiteren Öffentlichkeit wahrnehmbares Signal, dass angesichts von Grenzüberschreitungen (bspw. „das Gesicht vom neu-deutschen Juden- und Israelhass“) notwendig ist.“ uebermedien.de/111859/alles...

This in depth @cnn.com investigation is not an easy read, but the bottom line is clear: bulldozing dead bodies into unmarked mass-graves is irreconcilable with #IHL demands to respect the dignity of the dead and prevent them from becoming the missing. edition.cnn.com/2025/12/03/m...

A fascinating scene to understand how personalistic regimes work. First, there is an in-or-out decision by the leader. This is always in flux, deliberately uncertain and essential to extract rents and exert power. When you are on the inside the substance of what you say and do becomes secondary.

On the theme of #AHouseofDynamite How do we decide whether a nuclear missile attack is real ? Listen to Steve Fleming (@smfleming.bsky.social) telling the story of Stanislav Petrov. Is a nuclear war a taboo? Listen to Janina Dill (@janinadill.bsky.social) talking about the nuclear winter.

Let's be clear drawing and enforcing a "Yellow Line" across Gaza that civilians cannot approach/cross is incompatible with international law.

Podiumsdiskussion zu "Macht & Ohnmacht des Int. Rechts"; ein interessanter Einblick in den 🇩🇪 Diskurs zu Recht, auch bzgl Gaza, obwohl die recht kontroverse Diskussion mit dem Publikum nicht gezeigt wird ... mit Isabelle Ley & @ndeitelhoff.bsky.social www.youtube.com/watch?v=3zvE...

It's easy to see this speech as just weirdly performative, but there's a lot more—and a lot worse—going on here. The meeting & speeches are part of a larger project aimed at promoting the military leadership’s partisan alignment with the administration. How? 1/

In this post @tomdannenbaum.bsky.social & I trace how the Starmer Government's repeatedly misconstrues its obligations under the Genocide Convention in #Gaza, hiding behind a Court judgement that is years away with a position that we call "legally illiterate" and "morally indefensible".

A critical call to protect the #ICC in the face of looming US sanctions. As the current US administration is going rogue with sanctions, European states will need to come too grips with how to protect their nationals, their institutions and the rule of law.
