Chapter 3 assesses international anti-terrorism law during the Cold War, up to the late 1980s. It uses the archives of the UN General Assembly and the International Law Commission, where there was most activity on terrorism during that period. The chapter finds apparent conceptual departure but fundamental continuity from similar international legal activities in the previous era. In post-war consciousness the state was no longer portrayed as a victim of terrorism, but became a perpetrator, so the purpose of international law on terrorism was redrawn to provide a pacifying constraint between states rather than an architecture of collaboration.
