International relations is a dynamic discipline which tries to explain political activities across the state boundaries. According to Ola Joseph, “ International relations are the study of all forms of interactions that exist between members of separate entities or nations within the international system”.

International relations is concerned with all the exchange transactions, contracts, flow of information and the resulting behavioural response between and among separate organised societies. International relations could encompass many different activities such as social, economic, religious and others.

According to H.J. Morgenthau, Power is the key to international relations. He viewed that international relations are the subjects that deal with those relations among nations which involve power status. External developments constantly influence the domestic policies. Nations are compelled to enter into dialogues, form alliances with Other nations. This is to ensure the power and prestige of nations in the international system.

It is of immense importance for the student of international relations to understand that the world of today is marked by two factors. One is to do with the nature of power in the nuclear age and the other concerned with the interdependence of mankind.
