International studies have reached a considerable degree of autonomy from political science. Evidence of this autonomy can be found in the emergence and development of international studies programs in leading universities. However, this autonomy within the social sciences is hardly ever justified in scientific terms. Moreover, arguments presented by international studies regarding their object of study are often weak. The paper argues that the rise of neoclassical
realism, aiming at the explanation of foreign policy on the basis of the distribution of power (taking into account domestic politics), has the potential to reverse the autonomization of international studies. Perhaps inadvertently, neoclassical realism may invite us to revisit the autonomy of international studies and its relation with political science.
