Whether inside a revolutionary coalition or across a diplomatic bargaining table, the pattern repeats: accommodation is offered in the name of stability, and the authoritarian faction accepts the concession not as a settlement but as a staging ground for further domination. Four documented cases—revolutionary Russia, Iran, Republican Spain, and interwar Britain— trace the recurring miscalculations that enabled totalitarian forces to consolidate power.
