As was seen in analyzing Graph 3, individualism is largely displaced by statist ideas in the mixed-economy society, and human ends are accomplished largely through the government. Thus the populace is already accustomed to taking orders within a top-down power structure, a circumstance that expedites the militarization of the increasingly totalitarian state. If such a state becomes involved in large-scale military conflicts, then these wars are used to justify numerous new forms of intervention and nationalizations of more industries. These measures tend to remain in effect long after hostilities have ceased; in the United States, for example, "emergency" interventions passed during both World War I and World War II became permanent features of the statist system. The positive-feedback relationship between domestic and foreign interventionism is familiar to historians. Not only do the exigencies of war serve to rationalize new domestic controls and programs, but moreover the apparatus of domestic intervention is readily converted to military ventures abroad. Even since the end of the Cold War, for instance, the United States has shown a proclivity toward military intervention into numerous disputes around the globe.
