Brzezinski Chair in Global Security and Geostrategy

Advancing understanding in geostrategy, international security, and global politics

Zbigniew Brzezinski, the nation’s 11th national security adviser, applied his rigorous academic background to vexing policy questions. Following in Brzezinski’s footsteps, the Chair works to fuse academic insights with the needs of governments to promote a more secure and prosperous world. Our work examines how rising states are reshaping global order, how authoritarian regimes use hostage-taking and other coercive tools against democracies, how to measure the diplomatic power that shapes both, and how questions of identity drive conflict between and within states. Several of our projects are run in partnership with leading universities — Johns Hopkins SAIS on diplomatic measurement, Harvard on identity and conflict — translating sustained academic research into effective policy tools.
