The purpose of this monograph is to show that US counterinsurgency doctrine would benefit from greater emphasis on social, cultural, and political aspects of the operating environment, using the case of the Maoist insurgency in Nepal as an example. The concept of fourth generation warfare provides context with its focus on the application of political, economic, and social networks in modern conflict.
