Sovereignty
Cold War
Geopolitics
Accountability
Intervention
Legitimacy
Delayed justice

D2.His.14.9–12: Analyze multiple and complex causes and effects of events in the past.

D2.His.15.9–12: Evaluate the relative influence of various causes of events and developments in the past.

D2.Civ.12.9–12: Analyze how people use and challenge local, state, national, and international laws to address a variety of public issues.

Students analyze cause-and-effect relationships and evaluate competing explanations for historical outcomes. These skills align with nonfiction reading and analytical reasoning tasks found on PSAT and SAT assessments.

This lesson examines why the Cambodian genocide did not prompt rapid international intervention and why accountability was delayed for decades. Students analyze how Cold War alliances, fear of regional instability, and respect for sovereignty outweighed humanitarian concerns.

Global responses to mass violence today are often shaped by strategic interests rather than moral consensus. This lesson encourages students to consider how international law functions when enforcement depends on political will rather than obligation.
