This book investigates Ukraine's potential role as a regional security keystone in the post-Cold War era. Sherman Garnett, drawing on the country's size, location, diversity, historical ties, and recent resilience, argues that Ukraine could serve as a pivotal element in regional security. The study examines Ukraine's domestic politics, economic reforms, and foreign policy decisions concerning Russia and the West, aiming to correct common misconceptions and highlight the significant stakes involved in a stable Ukraine. Garnett proposes a more comprehensive, long-term U.S. and Western policy approach for Ukraine and the broader region, extending beyond immediate concerns like nuclear disarmament and NATO expansion.

The book posits Ukraine as a crucial security 'keystone' due to its geopolitical and internal characteristics. It advocates for a revised, long-term Western policy framework that acknowledges Ukraine's pivotal role beyond immediate security concerns. The analysis aims to correct common misunderstandings and underscore the importance of a stable Ukraine for regional security. The study's focus on policy recommendations suggests an intended audience of policymakers, academics, and those interested in international relations and Eastern European security.
