Supreme Command by Eliot A. Cohen is intelligently conceived and engagingly written. The subject is the fraught matter of civilian versus military control of strategy during wartime. Cohen provides four enlightening biographical essays of leaders who handled the conflict successfully: Clemenceau in WWI France, Lincoln in Civil War America, Churchill in WWII Britain, and Ben-Gurion at the birth of Israel. These mini-bios are set between an opening chapter examining the role of the Soldier and the State, based on Samuel Huntington's book of the same title, and three wrap-up chapters exploring the subject in the light of the profiles of the leaders. Cohen's very impressive skills as scholar, writer, and teacher are evident throughout this book.
Cohen notes that Huntington "laid out what he termed a theory of 'objective control,' which holds that the healthiest and most effective form of civilian control of the military is that which maximizes professionalism by isolating soldiers from politics, and giving them as free a hand as possible in military matters." This formulation came to be treated as the "normal theory of civil-military relations." The effect is the civil side decides that war is the option to pursue, and that the military will then take over the process. Then, "to ask too many question, (let alone to give orders) about tactics, particular pieces of hardware, the design of a campaign, measures of success, or to press" personnel decisions is "meddling and interference...inappropriate and downright dangerous."
In the first three profiles Cohen depicts the leaders within this "normal" framework. None of them fit: Clemenceau would visit the front lines weekly, interviewing soldiers and generals, and continually mediate conflicts between his leading generals; Lincoln pressured his supply chief to obtain repeating rifles, selected and fired generals, and set a spy to report on General Grant; Churchill is famous for his seemingly endless stream of "Action This Day" memos to both military and civil staff, like Lincoln, he fired generals, was actively involved with new technology, and helped set dates for campaigns. Ben-Gurion faced a much different situation: he was involved in creating a government for the forthcoming State of Israel, at the same time planning for the development of an armed force to face an expected war with the Arab World. To establish the new State, he hade to deal with the existing armed Jewish groups with different politics, goals, and abilities. Some of them were having shootouts with one another. His civil-military conflicts were different, but still challenging. His technique was heavy handed and abrasive, but he interacted extensively with the many players, in many cases serving as a teacher of both civil and military affairs.
Readers of military science and military history will find much of interest in the three concluding chapters. Cohen gathers views from a number of military historians who question the standard theory. Some question whether military strategy even exists, given the unique situations and unexpected developments that accompany any war. Cohen also discusses more recent American wars, citing how FDR operated during WWII, and LBJ in Vietnam. In the latter case, he states that the president, although he personally picked bombing targets in North Vietnam, didn't ask too many questions, but too few. The only answer seemed to be, more forces in the field. The political factors of the Gulf War and the Bosnia operations are also discussed. These chapters identify a rich array of additional reading, always a good thing, except for expanding the want-to-read list.
Highly recommended for the military history community, but insightful reading for anyone with an interest in the more political question of the interaction between civil government and the military.
