High Quality Content by WIKIPEDIA articles! Unrestricted Warfare is a book on military strategy written in 1999 by two colonels in the People's Liberation Army, Qiao Liang and Wang Xiangsui. Its primary concern is how a nation such as China can defeat a technologically superior opponent (such as the United States) through a variety of means. Rather than focusing on direct military confrontation, this book instead examines a variety of other means. Such means include using International Law (see Lawfare) and a variety of economic means to place one's opponent in a bad position and circumvent the need for direct military action.
