Weekend Roundup: September 20-26, 2014

This week on Opinio Juris, Jens, Jennifer Trahan and Julian discussed the international legal basis for the air strikes against ISIS. Jens also analysed why Khorasan is seen as a more immediate threat to the US than ISIS. For more on the US domestic legal basis, check out Deborah’s post with a snippet from her Daily Beast article on the perennial US War Powers fight.

A guest post by Anton Moiseienko gave some insights in Russian scholarship on the legality of Crimea’s annexation under international law.

Finally, Jessica wrapped up the news and I listed events and announcements.

Many thanks to our guest contributors and have a nice weekend
