NATO After Russia’s Invasion of Ukraine: Threat Perceptions and Their Consequences

When Russia began its full-scale invasion of Ukraine in February 2022, analysts and policymakers highlighted the unifying shock that NATO members experienced. Even before the return of U.S. President Donald Trump, however, beneath this seeming cohesion lay deep-seated differences in how member states perceive and prioritize security threats.

NATO After Russia’s Invasion of Ukraine analyzes six leading members of the alliance: the United States, the United Kingdom, France, Germany, Poland, and Italy. Through ninety-eight original interviews with policymakers and analysts, Jason W. Davidson demonstrates how divergent threat perceptions influence the NATO allies’ major defense decisions, such as how much they spend on defense, and which challenges are most important for the alliance moving forward. With the rise in tumultuous geopolitical challenges posed by Russia, China, terrorism, and mass refugee flows, this book provides the crucial context needed to navigate NATO’s evolving role in international security.

Jason Davidson is a Professor of Political Science and Director of the Security and Conflict Studies Program at the University of Mary Washington in Fredericksburg, Virginia. He is also a Nonresident Senior Fellow at the Atlantic Council’s Transatlantic Security Initiative.

Throughout this career, Professor Davidson has authored of five books, including NATO After Russia’s Invasion of Ukraine: Threat Perceptions and Their Consequences (Georgetown University Press, 2026), America’s Entangling Alliances: 1778 to the Present (Georgetown University Press, 2020), with Fabrizio Coticchia Italian Foreign Policy During Matteo Renzi’s Government: A Domestically-Focused Outsider and the World (Lexington Books, 2019); The Origins of Revisionist and Status-quo States (Palgrave Macmillan, 2006) and America’s Allies and War: Kosovo, Afghanistan, and Iraq (Palgrave Macmillan, 2011).
