In On Order, Authority, and Modern Civil-Military Relations, Lindsay P. Cohn presents a compelling challenge to the dominant normative framework in U.S. civil-military relations, questioning Huntington’s paradigm of military professionalism. By skilfully comparing and synthesizing Augustine's insights, democratic political theory, and social science research, Cohn illuminates the complexity of contemporary military ethics and roles within democratic societies. Her interdisciplinary approach, effortlessly weaving together centuries of literature with incisive analysis, invites deep reflection and offers a fresh perspective on the crucial normative foundations of modern civil-military relations.
