Council on Foreign Relations Adjunct Senior Fellow for National Security Studies Richard Betts and Adjunct Senior Fellow for Defense Policy Stephen Biddle, define and explain the concept of deterrence for CFR Model Diplomacy’s “Iran Deal Breach” and other CFR Model Diplomacy case studies. Model Diplomacy ( is a free multimedia simulation program that engages students through role-play to understand the challenges of shaping U.S. foreign policy in an interconnected world.

Deterrence, which has long existed, became more explicit with the dawn of nuclear weapons, whose destructive power poses special problems. Betts and Biddle evaluate arguments about deterrence’s relevance today and discuss the evolving U.S. deterrence strategy toward Russia and China.

Instructors interested in exploring “Iran Deal Breach” and other cases for their classrooms can visit the Model Diplomacy case library.
