National Interest: From Abstraction to Strategy
Dr Michael G Roskin
Monograph by the US Army War College, Strategic Studies Institute
"The "national interest" is a composite declaration derived from those values that a nation prizes most–liberty, freedom, security. Interests are usually expressed in terms of physical survival, economic prosperity, and political sovereignty. The list invariably expands, and is ultimately shaped by subjective preferences and political debate. As an object of political debate, the concept of national interest serves to propose, justify, or denounce policies."
