Nevertheless, the same changed world conditions and the advance and spread of new technologies that are complicating applied deterrence today may also open the door to a new synthesis in deterrence thinking. The key may be the use of improved analytical concepts and tools to better understand the multiple dimensions of strategy including different domains and the impact of culture and psychology.
