Military assistance is a recurring U.S. security tool despite its history of mixed results, yet it remains bureaucratically cookie-cutter. The authors of "War at Arms Length" argue that success depends on two factors: interest alignment and defense-institution capacity. They contend that the U.S. must transition from a "weapons-first" approach toward "institutions-first" sequencing to avoid entrapment in misaligned missions.

The authors provide a logical, conditional framework that successfully demystifies why some military aid succeeds while other programs languish or backfire. While their advice to favor institutional reform over hardware is sound, they are less convincing on whether bureaucracy can be forced to abandon its preference for big-ticket weapons without significant congressional upheaval. Watch this video if you want the nuance behind the case studies; the summary is comprehensive, but the authors’ candid discussion of the "cookie-cutter" errors they see in current state-building programs offers useful context.
