Counterinsurgency, now joined with the newer label "low intensity conflict," is back in official fashion, but serious studies of the subject remain few. This effort to remedy that lack relies on three case studies-Greece, the Philippines and Vietnam before 1965. It is thought-provoking, much more so in its discussion of cases than in its broad conclusions, which sound like the liberal cant about Vietnam: American policymakers "have misunderstood the sources of insurgency . . . and overestimated the United States' role as an outside promoter of security and development."
