Influenced in part by the writings of Sun Tzu, Carl von Clausewitz, Henri Jomini, and other strategists, most major militaries have adopted principles of war that are widely promulgated. Marvin Pokrant argues that these commonly accepted principles fail to reflect the ideas that led to them. Looking at the fundamental and enduring concepts behind the original principles of war, Pokrant presents nine new principles of war. To illustrate his points Pokrant uses numerous examples drawn from military history, including land, sea, and air warfare from ancient times to the present. By analyzing and reforming the principles of war, Pokrant provides a modern, relevant, and useful way to guide decisions made in times of war.
