Indeed, leading Classical Realist Hans J. Morgenthau defined politics among states (nations) as “struggle for power and peace” (Morgenthau, 1948). For him, power for states is a tool and an objective at the same time in order to protect and project their interests. As interests can be subject to change and increase, then foremost interests of states always are to seek more power. Actually, for Morgenthau, international politics is all about power politics.
