Realist perspective views survival and security of state as supreme national interest in international system characterized by anarchy. Each nation state attempts to maximize its power to promote its national interest at the expense of others. The international system is defined in terms of great powers like bipolar, unipolar and multipolar world and that great power tends to exercise hegemony. Any foreign policy and decision of political leaders must be assessed in terms its outcome. This perspective became dominant framework for explaining foreign policy behavior after Second World War. Scholars and experts do believe that Indian foreign policy orientation has always been realist and pragmatic despite Nehru idealism and policy of non alignment. This realist orientation got more man ifest and profound expression after collapse of Soviet Union in 1990.
