This summer, during a trip to Asia, U.S. Secretary of Defense Pete Hegseth reiterated that the Indo-Pacific is the U.S. Department of Defense’s priority theater. Yet unlike Europe, the region still lacks a multilateral defense alliance, relying instead on a patchwork of bilateral ties and minilateral arrangements.

In this episode of Pivotal States, Christopher S. Chivvis speaks with Dr. Ely Ratner of the Marathon Initiative to unpack the risks and benefits. Dr. Ely Ratner, who served as Assistant Secretary of Defense for Indo-Pacific Security Affairs for the Biden administration, lays out his vision in a recent Foreign Affairs essay, “The Case for a Pacific Defense Pact.”
