It is my great pleasure to announce that Jens Ohlin, Professor of Law at Cornell, is joining Opinio Juris as its newest masthead member. (Astute readers will have noticed he was added there yesterday!) I doubt Jens needs much introduction, but here is a snippet from his Cornell bio anyway: Professor Ohlin specializes in international law and all aspects of criminal law, including...

Your weekly selection of international law and international relations headlines from around the world: Africa Somali and African Union forces have launched a long-awaited fresh offensive against al-Shabab fighters aimed at capturing remaining ports from the armed group, army and government officials have said.

As the military situation in eastern Ukraine become more violent with the incursion of Russian troops, Vladimir Putin has called for talks to determine the statehood of eastern Ukraine. The Interpreter, a website that translates and analyzes Russian media reports, states that in an interview on Russian television Putin said: We must immediately get down to a substantial, substantive negotiations, and...

This week on Opinio Juris, Julian asked whether the US President can enter into a legally binding climate change agreement without Congress, and educated news agencies about the difference between Taiwan's airspace and its Air Defense Identification Zone. The main focus this week was on the Middle East. Kevin commented on an Al Jazeera America piece on Israel's attack on Shujaiya, while Peter discussed the...

I’ve been impressed by the number of questions I’ve fielded in the past few weeks from students, colleagues and media alike about whether the United States can and/or should pay ransoms or exchange prisoners for Americans held by various groups overseas. (I discuss the issue in short clips here and here.) Why did we exchange prisoners to rescue Bowe Bergdahl, but refused to pay ransom for James Foley? Is it illegal to pay ransom to these groups, or just a bad idea? Is it really a bad idea? In the interest of consolidating some answers on a topic that raises a complex cluster of issues, I thought it worth summarizing some of them here – first on the topic of ransom for hostages taken by terrorist groups, then on the topic of prisoner exchanges more broadly. The upshot: It may well be the right policy decision in an individual case for a government not to pay ransom to a terrorist group, but the broader, categorical statement that “we don’t negotiate with terrorists” is neither historically accurate nor strategically wise.

It's only a matter of time before we start seeing proposals to take away the citizenship of Americans fighting for ISIS/ISIL forces in Syria and Iraq. They have drawn renewed attention in the wake of James Foley's beheading (apparently by a British citizen) and the death, reported at length today in the NYT, of American Douglas McCain in Syria. Several...

The New York Times is running a big report today on the U.S. plan to sign a "sweeping" climate change agreement without having to go to Congress for approval or ratification.  Instead of a typical treaty requiring ratification by the Senate, the U.S. has a different more creative strategy. American negotiators are instead homing in on a hybrid agreement — a proposal...

Your weekly selection of international law and international relations headlines from around the world: Africa Families hiding infected loved ones and the existence of "shadow zones" where medics cannot go mean the West African Ebola epidemic is even bigger than thought, the World Health Organisation has said.

This week  on Opinio Juris, we had the final instalments of our Emerging Voices symposium, with a post by Tamar Meshel on awakening the "Sleeping Beauty of the Peace Palace" and one by Mélanie Vianney-Liaud on the controversy surrounding the definition of the Cambodian genocide at the ECCC. More definitional issues arose in Kevin's post discussing Britain's expanded definition on terrorism, which now includes watching the video...

Just keeping up with the news on international terrorism/counterterrorism this summer could be a full time job. Among many other potentially significant reports, I wanted to highlight this statement recently released by Al Qaeda in the Arabian Peninsula (AQAP), often described by U.S. officials as the branch of Al Qaeda that currently poses the greatest threat to the United States....
