Compared to domestic politics, foreign policy has fewer decision makers and is more policy driven.

Foreign Policy includes all interactions of individual nation - states with other states. In the wake of globalization, in the 21st century it is particularly important, owing to the interdependence of states. With the advent of international society and globalization implications of foreign policy for each nation-state are far greater. The study of Foreign Policy therefore has become ever more critical and important. The study of Foreign Policy is not limited to any particular school of social science but is a relevant subject for all. In International Relations this study is particularly important as foreign policies form the base for international interactions between individual states.
