Book excerpt: Based on cutting-edge research by an interdisciplinary team of academics and policy analysts, this insightful and timely book considers the role of great power competition in what has come to be known as gray zone conflict. Taking the 2022 Russian invasion of Ukraine as a backdrop for some of its critical evaluation, it also examines US and NATO approaches to the management of escalation in asymmetric conflicts, and proposes innovative tools for managing crises in the future.
