War at Arm’s Length: Can Military Assistance Work?

U.S. military assistance often has a bad reputation, but it isn’t doomed to failure. This episode examines why security assistance succeeds with some partners and falls short with others, and what it takes to turn weapons and training into lasting military capability. Lieutenant General (Ret.) Charles Hooper, Dr. Richard Bennet, and Dr. Alexander Noyes are the guests.

Today’s episode explores how the United States can build effective military partners, drawing on Richard Bennet and Alexander Noyes’s book, War at Arm’s Length: How America Can Build Effective Partners Through Military Assistance (Yale University Press, 2026).

Our guests begin by asking what effectiveness means, when security assistance advances U.S. interests, and how Washington should assess the results. Bennet and Noyes explain the book’s central argument that shared security interests and capable defense institutions make assistance more likely to succeed. The discussion then examines how far sustained assistance and personal relationships can bring partners’ interests closer together, and how much alignment is needed at the outset. Drawing on cases including Ukraine and Colombia, the guests explore the importance of partners’ willingness to reform and the limits of externally imposed change. The episode closes with recommendations for choosing partners, coordinating U.S. assistance, and sequencing support so that institutions can sustain the capabilities Washington helps provide.
