“This book deals with a great issue of constitutional government—how to allocate the power to make war. Only Congress can declare war, but formally declared wars are rare. The interesting questions under our Constitution concern how it allocates the power to engage in undeclared hostilities, or to authorize military or diplomatic measures that may lead to war. As Edward Keynes’s subtitle suggests, these issues are in the ‘Twilight Zone of Constitutional Power’. . . . The book is well written and interesting. The summary of the litigation sparked by the war in Vietnam is valuable.”—Judge Abraham D. Sofia American Historical Review
