Realism theory
Realism is often associated with Realpolitik, as both deal with the pursuit, possession, and application of power. Realpolitik, however, is an older prescriptive guideline limited to policy-making, while realism is a wider theoretical and methodological paradigm to describe, explain, and predict events in international relations. As an academic pursuit, realism is not tied to ideology; it does not favor any particular moral philosophy, nor does it consider ideology to be a major factor in the behavior of nations. Priorities of realists have been described as Machiavellian, single-mindedly seeking the power of one's own nation over others.
