The concept of power is known to be one of the core components to understanding international relations, through the ability to influence and the achieving of objectives this is how countries are successful. Power can be identified through military strength, economic wealth, natural resource and, size of territory. The importance of having power is crucial as it allows states in world politics, the ability to pursue certain interests and gain influence on an international scale, power is often known to be a attribute of a state. Harvard professor, Joseph Nye identified the categories of power within his book The Annals of the American Academy of Political and Social Science which include: Hard power, the use of force when achieving ams. Smart power, use of force, persuasion and influence to achieve aims and finally soft power, the use of influence or persuasion. Realists argue that states use hard power in order to gain and maintain for their own use, John Mearsheimer wrote “States compete with each other to gain power at the expense of others to make sure they do not lose power” this quote can be similar to Morgenthau’s definition of power in which he states “Power may comprise anything that establishes and maintains the power of man over man …from physical violence to the most subtle psychological ties by which one mind controls another” Morgenthau believed that the only power that was important was hard power through military force, he explains that power is determined by the political and cultural environment in which there is a constant competition for power. Classic realism relies heavily on the balance of power and rationality unlike structural realism. Whereas, Waltz’s definition of power provides a scientific explanation for the current global political system “

Walzt’s theory of realism can be broken into two parts in which claims that states exists within an anarchic system where politics takes place in an arena without any central authority thus leading to countries pursing power for security and protection.
