Murphy is the Manatt/Ahn Professor of International Law at George Washington University.] Harold Hongju Koh has produced an unabashedly progressive manifesto that seeks to explain why it is that many of the initiatives of the early Donald Trump administration relating to transnational affairs have not achieved their objectives, while simultaneously laying out a “counterstrategy of resistance.” To this end, Koh employs...
