The Inheritance: America's Military After Two Decades of War

Episode 127 of the Irregular Warfare Podcast explores the lasting impact of the Global War on Terrorism and what the United States has inherited—militarily, politically, and socially—after twenty years of conflict in Iraq and Afghanistan.

Our guests begin by examining how the U.S. military has historically navigated post-war transitions, particularly following protracted irregular conflicts. They then evaluate the consequences of the post-9/11 wars on the military institution, the broader national security establishment, and American society at large. The episode concludes with a forward-looking discussion about the strategic lessons learned and what they might mean for future great power competition and conflict.

The Honorable Mara Karlin is a Professor of Practice at the Johns Hopkins School of Advanced International Studies. She has held senior national security roles for six U.S. Secretaries of Defense and most recently served as Assistant Secretary of Defense for Strategy, Plans, and Capabilities. Her newly published book, The Inheritance: America’s Military After Two Decades of War, anchors today’s discussion.

Major General (retired) John Ferrari is a nonresident fellow at the American Enterprise Institute. He focuses on the defense budget, reform, and acquisition, and previously served as director of program analysis and evaluation in the Army. Over his 32-year military career, he also served as a strategic planner for Operation Iraqi Freedom and as a deputy commander at the NATO Training Mission in Afghanistan.
