The estimable professor-pundit Daniel Drezner has a typically smart blogpost on President Trump's refusal to affirm the U.S. commitment to Article 5's collective defense provision of the North Atlantic Treaty. I don't have a problem with his views here, but I can't help jumping in to correct this paragraph from his post: So why is this such a big deal of a story? The United...
I read Jennifer Trahan's post yesterday with great interest -- but not surprisingly I disagree with it. Before I get to my disagreements, though, I think it's bizarre that we are all debating the legality of unilateral humanitarian intervention in the context of the recent US missile attack on Syria. It simply beggars belief to think that the attack was in any way motivated...
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...
As discussed in my previous post, last month I was privileged to organize a conference at Notre Dame’s London Global Gateway on the topic of UK trade and Brexit. I discussed the first session in my previous post, which addressed UK trade negotiations with the EU.

On November 7, 2016 I was privileged to organize a conference at the University of Notre Dame’s London Global Gateway on the topic of UK trade and Brexit. The conference had three sessions: (1) UK trade negotiations with the EU; (2) UK trade negotiations outside the EU; and (3) UK’s post-Brexit status within the WTO. The participants were...
Urbanization is our present and it is our future. Between the recently completed UN Habitat III conference in Quito, Ecuador, and Iraqi Special Operations entering Mosul, starting what may be a complex urban battle, we face constant reminders that much of the world’s population now lives in cities. How we protect rights, foster development, interact with the environment, organize politically,...
Early in my international law education here in the U.S, I learned that dualism was an unfortunate concept that led to the U.S. violating international law obligations by failing to enforce those obligations (usually treaties) domestically. But today's blockbuster decision from a UK court in Miller v. Secretary of State on Brexit should remind us that dualism can also work to...
I want to call readers' attention to Oxford University Press's publication of my friend Kim Priemel's new book, The Betrayal: The Nuremberg Trials and German Divergence. Here is the publisher's description: At the end of World War II the Allies faced a threefold challenge: how to punish perpetrators of appalling crimes for which the categories of 'genocide' and 'crimes against humanity'...
[Laurence R. Helfer is the Harry R. Chadwick, Sr. Professor of Law at Duke University and a permanent visiting professor at iCourts: Center of Excellence for International Courts at the University of Copenhagen.] As the world reacts to the shock of the Brexit referendum, international lawyers are turning their attention to the mechanics of Britain’s departure from the EU. Article 50 of...
As the news of the Brexit vote sinks in, commentators are considering the various longer-term effects. I want to highlight the how this may look to the EU’s neighbors to the east, especially countries such as Ukraine, Moldova, and Georgia that have recently signed Association Agreements with the EU. Ukraine and Moldova, in particular, have electorates that are divided over...
I know Opinio Juris is probably not where you come for sports updates but this is the result of the ConIFA World Football Cup, a tournament among unrecognized regimes, minorities, and stateless peoples. For more on ConIFA, statehood, and nationalism, see my post from last week. In short, the ConIFA competition may be an attempt not only to boost morale within...
States and nations are not the same thing. A nation is a "people," itself a difficult concept to define under international law. A state is a recognized political entity that meets certain criteria. International lawyers will tell you that the characteristics of statehood include a defined territory, a government, a permanent population, and the ability to enter into foreign relations. State...
