This article is about the theoretical discipline. Constructivism, however, is increasingly becoming mainstream. These thinkers were later described as “Idealists”. The leading critique of this school of thinking was the “realist” analysis normative theories of the media pdf by Carr.

However, a more recent study, by David Long and Brian Schmidt in 2005, offers a revisionist account of the origins of the field international relations. They claim that the history of the field can be traced back to late 19th Century imperialism and internationalism. We should once and for all dispense with the outdated anachronistic artifice of the debate between the idealists and realists as the dominant framework for and understanding the history of the field”. Their revisionist account claims that, up until 1918, international relations already existed in the form of colonial administration, race science, and race development. A clear distinction is made between explanatory and constitutive approaches when classifying international relations theories. Explanatory theories are ones which postulates the world is something external to theorize about. A constitutive theory is one which suggest that theories actually help construct the world.

Early realism can be characterized as a reaction against interwar idealist thinking. There are various strands of modern-day realist thinking. However, the main tenets of the theory have been identified as statism, survival, and self-help. Realists believe that nation states are the main actors in international politics.

As such it is a state-centric theory of international relations. Realists believe that the international system is governed by anarchy, meaning that there is no central authority. Therefore, international politics is a struggle for power between self-interested states. Realists believe that no other states can be relied upon to help guarantee the state’s survival. Realism makes several key assumptions. Thus, states, as the highest order, are in competition with one another. That level of power is in turn determined by the state’s military, economic, and political capabilities.

It is, however, only one strand of neorealism. This strand of theory is sometimes called “modern realism”. Waltz’s neorealism contends that the effect of structure must be taken into account in explaining state behavior. Waltz also challenges traditional realism’s emphasis on traditional military power, instead characterizing power in terms of the combined capabilities of the state. For example, an idealist might believe that ending poverty at home should be coupled with tackling poverty abroad. Wilson’s idealism was a precursor to liberal international relations theory, which would arise amongst the “institution-builders” after World War II. Liberalism holds that state preferences, rather than state capabilities, are the primary determinant of state behavior.
