Realism is one of the important ideas about global politics, about conservative social philosophy and political philosophy (Heywood 2011: 54; Shimko 2013: 36). Furthermore, Gilpin (1996) argues that "Realism ... this is not a scientific theory of tampering tests, so we can not prove and refute" (Frankel 1996: xiii). Discuss the components of realistic international relations approach. First, the state is an important part of the concept of realism.
Underlying the realistic approach to international relations is the pursuit of power by the state and the hegemony of the state. Realism thinks international relations is not like a thing to study things, but how to study it. You can distinguish "economic people", "religious people", "moral people", "politicians" and so on. To understand politics, you only need to study political behavior of politicians as a state synonym. The theory of political realism is based on the concept of a rational subject. You should compare real events with this ideal standard image. Realism begins with the principle that the state must keep its safety by accumulating violent means. Necessity is common as the main concept in realism theory. Today's concept of realism developed in response to the ideals of liberal ideals after the First World War.
In 1979, Kenneth Waltz announced "International Political Theory". Since then, a new realistic approach to international relations has been born. He tried to develop a more rigorous international political theory than earlier realists like Morgenthau. Waltz's paradigm insists that "classical realism understands constraints inherent in disorder, but does not seriously explain its structure." In addition, he shows how to distinguish between cellular and structural elements and establish a relationship between them. Waltz not only limits the theory he produces, it also limits its scope. He thinks that these patterns are products of the system itself, not products of subsystems.
