“The [realist] tradition focuses on the nationstate as the principle actor in international relations and its central proposition is that since the purpose of statecraft is national survival in an hostile environment, the acquisition of power is the proper, rational and inevitable goal of foreign policy (Evans and Newnham, 1998: 465). In this view, international arena is the scene of power politics and power, in that matter, it is conceptualized as both a means and an end in itself. In other words, international actors, nation-states notably, seek to gain power and it is this power what helps them survive in this environment in which reigns homo homini lupus est (man is wolf to another man) principle.
