In this episode of Asia Insight, we explore a recent NBR research project that examined the cumulative impact of three trends—the evolution of the Indo-Pacific geopolitical landscape, recurring questions about U.S. alliance commitments, and domestic political debates on nuclear armament—on the sustainability of U.S. extended deterrence and nuclear restraint in Australia, Japan, and South Korea.

Zack Cooper is the project’s Principal Investigator, and he is also a Senior Fellow at the American Enterprise Institute.
