In this episode of The World Unpacked, Isaac B. Kardon sits down with Ashley J. Tellis, Tata Chair for Strategic Affairs and Senior Fellow at the Carnegie Endowment for International Peace, and Andrew Yeo, Senior Fellow and the SK-Korea Foundation Chair at the Brookings Institution. They explore how the role of overseas bases has changed over time and how the U.S., China, and Russia—among other countries—use them to project power today. Despite advances in technology and long-range weapons, bases remain key to grand strategy, political influence, and sustained military reach.
