Issues of national security and intervention have always been a source of tension and disagreement among classical liberals and libertarians. This reading group will explore a variety of issues related to war, security, and liberty from an economic perspective. The topics covered will include: common justifications for state-provided security, the political economy of foreign intervention, the origins of the permanent war economy in the United States, the perverse incentives created by the military contracting process, and the negative effects of foreign intervention on the liberties and freedoms of U.S. citizens.
