How do insurgent groups win wars against powerful, well-financed nation-states? What does the "McDonald's theory" have to do with peacekeeping? Why did the British, French, and Soviet Union empires collapse after World War II? How have new weapons and technologies reconfigured the rules of the battlefield?
