I am getting a lot of questions about whether Trump's threats alone are illegal. The answer is yes. 1. First, Additional Protocol I states “Acts or threats of violence the primary purpose of which is to spread terror among the civilian population are prohibited.” (also DOD LOW Manual §5.2.2) 1/

Out tomorrow! Will middle powers like Canada and the Netherlands defend the values of international law in the context of the US/Israel attack on Iran? We discuss with @markkersten.bsky.social + Otto Spijkers the complicated relationships these states have with accountability.

Considering the Supreme Court just held that IEEPA never allows the president to impose tariffs, I'm keen to see the statutory basis for such an action.

"The Government of Spain will not applaud those who set the world on fire just because they show up with a bucket. What’s needed now: diplomacy, international legality, and peace.” - Spanish PM Pedro Sanchez on Iran-US ceasefire: www.aa.com.tr/en/world/spa...

I spoke to the Christian Science Monitor about Trump's threats to carry out mass war crimes. Though there appears to be a ceasefire (thank goodness), the threats have done irreparable damage to U.S. standing and moral authority. We will pay the cost for decades. www.csmonitor.com/World/2026/0...

“At al-Aqsa hospital, a colleague of Aslan said the vehicle he was driving was clearly marked w the WHO's logo on all sides, & that it had been at the front of a co-ordinated convoy transporting patients to the Rafah crossing when it came under fire from an Israeli tank.” www.bbc.com/news/article...

To center efforts for accountability and the plight of civilians following the invasion of the country as well as the ongoing violence waged its people and infrastructure, #Lebanon should join the #ICC. My latest for @aljazeera.com: www.aljazeera.com/opinions/202...

I joined more than 100 US-based experts in international law to call out the illegality of our government’s strikes on Iran: Over 100 International Law Experts Warn: U.S. Strikes on Iran Violate UN Charter and May Be War Crimes www.justsecurity.org/135423/profe...

Excellent article by @mollyquell.bsky.social providing an overview of the latest developments concerning the investigation into alleged misconduct carried out by ICC Prosecutor Karim Khan apnews.com/article/icc-...

Russia, China and France on Thursday effectively stymied a push by Arab countries to get the UN Security Council to authorize military action against Iran to reopen the Strait of Hormuz, saying they opposed any language authorizing force, according to a diplomat and a senior UN official.

NEW: On the first day of the war with Iran, the United States used a new ballistic missile. It was untested in combat. Our analysis shows it struck a sports hall, an elementary school, and residential areas — killing at least 21 people, including children. w/ @johnismay.bsky.social

For the first time, the International Court of Justice has ordered the publication of provisional measures compliance reports in The Gambia v Myanmar. @sabeehkhayyat.bsky.social unpacks this change in practice and explores how it may enhance the transparency and legitimacy of the Court.

Two new videos have emerged showing the deadly strikes that hit an IRGC compound, as well as an adjacent girls’ school, in Minab, Iran. By geolocating and verifying the footage, Bellingcat found two waves of attacks, occurring hours apart. www.bellingcat.com/news/2026/03...

This is the way.

AI executives and researchers “readily admit that they have not yet released a model that writes well,” Jasmine Sun writes. She speaks with AI experts about why LLMs are built in a way that is antagonistic to great writing:

The Iranian ppl are “under attack from their own regime. They’re under attack from the US & Israel. So as such, it’s really the Iranians, their livelihoods, their lives, their cultural heritage, all of that that is being destroyed.” www.theglobeandmail.com/world/articl... @janicedickson.bsky.social

This should be a bigger story. Because it’s not just about coercion. It’s not just about illegality. It’s about cruelty.

Munition remnants from a strike that killed 17 people in Tiné, Chad, on Wednesday, appear to match a model previously used by Sudan’s Rapid Support Forces (RSF) in the war with Sudanese government forces – despite RSF denials of involvement in the incident.

This is big. It doesn't just happen. Germany has been a stalwart supporter of Israel, despite clear evidence of its violations of the Genocide Convention in Gaza. The decision not to intervene at the #ICJ is likely bc its best lawyers have told Berlin that doing so can't help a lost case.

BREAKING: Germany has just retracted its intention to intervene in the Gaza genocide case (they can't step away from their arguments in the Myanmar case simply because now Israel is being accused, meaning that it rather says nothing than something that is detrimental for Israel)

"Europe’s response so far has not matched the gravity of the situation. Too often, concern for economic consequences has taken precedence over a principled defence of judicial independence and international justice." Slovenia asks EU to protect ICC judges sanctioned by US: efe.com/en/latest-ne...

Such attacks would entail war crimes and crimes against humanity, as is exemplified by the reference to parallel practices in Gaza in the ICC’s announcement of arrest warrants for Netanyahu and Gallant.

And they are still targeting hospitals … www.theguardian.com/world/2026/m...

Who funded most of the aid to Ukraine in their efforts to fight off Russia? Data from @kielinstitute shows nicely that Europe has indeed stepped up. The US relationship with Ukraine was on the way down but now Ukrainians teach the US all about drone warfare.

Is the war against Iran also fueled by a dangerous civilizational ideology? PAVLOS ELEFTHERIADIS argues that the Trump administration’s rhetoric about “Western civilization” revives an old logic of domination that threatens the foundations of international law. verfassungsblog.de/the-enduring...
