About the Author

Carrie Shirtz is a distinguished international relations scholar and author whose work illuminates the evolving role of global alliances in an interconnected world. With a PhD in Political Science from Georgetown University and extensive experience as a policy advisor to NATO member states, Shirtz brings a sharp analytical lens to the complexities of security dynamics. Her seminal book, NATO: From Regional to Global Security Provider, traces the alliance's transformation from a Cold War bulwark to a pivotal force in addressing transnational threats like cyber warfare and climate-induced conflicts. Shirtz's insights, drawn from years of fieldwork in Europe and the Middle East, offer readers a nuanced understanding of how multilateral institutions adapt to foster stability amid geopolitical upheaval. A frequent contributor to Foreign Affairs and lecturer at the Wilson Center, she continues to shape discourse on international security.
