New working paper with @janinadill.bsky.social: "The Moral Logic of Blame for Civilian Casualties": In survey & interview data, residents of Mosul Iraq penalize the intentional killing of 5 civilians more than the unintentional killing of 125, & blame is not zero-sum: papers.ssrn.com/sol3/papers....

Everyone who uncritically repeats "hospitals used for military purposes become legitimate targets" has a role to play in this epidemic of attacks against healthcare facilities in war! A) The law is more demanding than that! B) Without concrete evidence for "use" attacks are presumptively illegal.

From Ukraine and Sudan to Gaza: why have hospitals become a target of war?

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.

Greeted as Liberators?

How Americans think about U.S. military interventions.

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.

New episode of JIB/JAB - a fascinating and important discussion with @janinadill.bsky.social and @monicahakimi.bsky.social on how the attacks on Iran impact the crisis in int'l law, what follows, and how legal scholars and states should respond. Wherever you get your podcasts, or link in comment:

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...

It was a privilege to join forces with @bechamilton.bsky.social to write this piece on the Iran war in response to Yuval Shany and Amichai Cohen Aggression, Plain and Simple @justsecurity.org www.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...

Is the UK's intervention in Iran war legal?

Starmer said Britain would intercept Iranian missiles and allow US to use its bases in defensive action. Does that make the UK complicit in an illegal war?

middleeasteye.net

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...

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.

Antje Wiener@antjewiener.bsky.social · 5mo ago

Not really. Saying one thing in Parliament and deciding to let US American military use British airbases to launch their weapons against Iran shows clear support of US American international law violations in action on behalf of the British government. @janinadill.bsky.social @goldmatt.bsky.social

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
