These chapters are about events by which international law is marked, and through which it has registered and acquired force. At the outset, the editors asked contributors to explore some path not taken in international law’s development, with a view to understanding its contemporary resonance. This could be a mental exercise: let us think how international law would look today if it had come to a fork in the road and taken the other road. Another way to go about the task would be to perform the act of going back in time and taking the other road. This chapter is about the Women’s International War Crimes Tribunal for the Trial of Japan’s Military Sexual Slavery, which did just that (TWT 2001).2
