Pages 14

Realism is still the most venerable-and scrutinized-theoretical approach to the study of international relations and American foreign policy. As such, it is important to know what realism is and what it is not. This chapter discusses briefl y how realism contrasts with other approaches such as liberal and constructivist studies of American foreign policy. The bulk of the chapter then deals with the dimensions and diff erences of four types of realism-classical realism, neo-realism, defensive realism, and off ensive realism.
