This morning President Trump tweeted that "Germany owes vast sums of money to NATO & the United States must be paid more for the powerful, and very expensive, defense it provides to Germany!" But that's not how NATO commitments work. And so this afternoon, former US Ambassador to NATO Ivo Daalder gave President Trump a tutorial in nine tweets. Maybe we can...

It is difficult to overstate the horrors the US inflicted on Cambodia from the air during the Vietnam War: 230,000 sorties involving 113,000 different sites; 500,000 tonnes of bombs, as much as the US dropped in the entire Pacific theatre during WW II; at least 50,000, and probably closer to 150,000, innocent civilians killed. Even worse, that bombing campaign, along with...

As has been widely reported, 17 international-law scholars -- including yours truly -- recently submitted a 105-page communication to the Office of the Prosecutor alleging that Australia's treatment of refugees involves the commission of multiple crimes against humanity, including imprisonment, torture, deportation, and persecution.

Here is the abstract: This article portrays the use of consensus claims, as well as their substantiation, in the debate on cyber-attacks...

I have been following with great interest the debate at Just Security between Adil Haque and Jonathan Horowitz over whether the existence of a non-international conflict (NIAC) exists the moment a state launches a "first strike" at an organized armed group or whether hostilities of a certain intensity between the two are required. Adil takes the former position (see here, here, and here);...

The inimitable David Bosco dropped quite the bombshell yesterday at FP.com: The Office of the Prosecutor at the ICC intends to open a formal investigation into the situation in Afghanistan -- a situation that includes, as the OTP discussed in its most recent preliminary-examination report, US torture of detainees between 2003 and 2005. I'll have more to say about the...

Just Security published a very interesting post yesterday entitled "Military Attacks on 'Hospital Shields': The Law Itself is Partly to Blame," which seeks to explain why deliberate attacks on hospitals are becoming increasingly common -- in Syria, in Yemen, and elsewhere. The authors acknowledge that deliberate attacks on hospitals are almost always unlawful under IHL, because they violate the principle...
