Machines don't fight wars. Terrain doesn't fight wars. Humans fight wars. You must get into the mind of humans. That's where the battles are won. - COL John R. Boyd
Unrestricted Warfare by Senior Colonel Qiao Liang and Senior Colonel Wang Xiangsui, PLA
Unrestricted Warfare (超限战, literally "warfare beyond bounds") is a book on military written in 1999. 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.
