In the wake of Obama's memorable statement, a number of bloggers have questioned whether the Boston bombings deserve to be labeled "terrorism." Most of those bloggers -- such as the excellent Ali Abuminah here -- emphasize that many US definitions of terrorism require the violent act in question to be politically or ideologically motivated, which is still an open question with regard...

With the steady stream of posts on Kiobel in the past 24 hours, you may have lost track of it all. So here is a little insta-roudup with links to all the posts we've had so far (there'll be more in the regular roundup on Saturday). To start, you can find the opinions here.

We have invited several academic luminaries to post here at Opinio Juris over the next few days about the Supreme Court's decision in Kiobel.

This week we're hosting a symposium on Economic Foundations of International Law, the new book by Eric Posner and Alan Sykes. Here is the abstract: The ever-increasing exchange of goods and ideas among nations, as well as cross-border pollution, global warming, and international crime, pose urgent questions for international law.
