This book investigates the evolving strategic partnership between Russia and Iran, questioning how their shared opposition to Western hegemony shapes their cooperation across multiple regional conflicts. Nicole Grajewski, a fellow at the Carnegie Endowment for International Peace, utilizes extensive research into diplomatic, military, and economic records to analyze this bilateral relationship. She argues that the alliance is not merely transactional but represents a calculated effort to challenge the existing international order through coordinated defiance in theaters such as Syria and Ukraine.

Experts identify this work as a critical contribution to understanding the shifting alliances of the 21st century. Readers frequently note the clarity of the prose and the depth of the geopolitical analysis provided by the author.
