Since 1798, when Congress authorized John Adams to employ the navy to capture armed French vessels preying on American shipping on the Atlantic coast, U.S. presidents have grappled with the crucible of war. Some have dealt with it skillfully while others have tended toward the inept. Some have wanted to exert their war powers while others have shied away from them. Some have been successful while others have not. Never having had their authority clearly defined, the presidents, as commanders in chief, have been allowed to interpret the scope of their involvement in wartime decision making. The question of whether a president can order forces into combat against another nation has never been resolved and precedent supports both sides. "Essentially," says Raymond O'Connor, "the president can do whatever he can get away with." Commanders in Chief, offering a look at the president's constitutional and political roles during wartime, brings together the work of prominent historians. These experts analyze the war powers of the presidency as well as the wartime leadership of six presidents--William McKinley, Woodrow Wilson, Franklin Roosevelt, Harry Truman, Lyndon Johnson, and Richard Nixon. Two of the authors take revisionist views of their subjects. Lewis Gould asserts that McKinley delivered able and talented leadership during the Spanish-American War, while Robert Ferrell criticizes Wilson's leadership during World War I. On the other hand, Warren Kimball confirms the high ranking by most scholars of Roosevelt as the most gifted wartime chief executive of the twentieth century, and Clayton James substantiates Truman's feisty and pragmatic leadership in two conflicts. In Frank Vandiver's essay on Johnson and Stephen Ambrose's on Nixon, the authors emphasize the diversity of challenges the two presidents faced during the controversial Vietnam War. --From publisher's description.
