Gulf Kaleidoscope: Reflections on the Iranian Challenge analyzes potential U.S. strategies toward Iran and how different international actors are likely to respond to the U.S. pursuit of those strategies. Succinct chapters describe three principal approaches toward Iran: engagement, containment, and deterrence. The volume then goes on to analyze how key parties—Israel, Iran’s Gulf Arab neighbors, and the rising powers of Turkey, China, India, and Russia, as well as the Iranians themselves—would likely respond to each strategy.
