The initial discrepancy of "Neorealism" and "Neoliberal Institutionalism" reffers to the matter of cooperation in international relations. This is because, the first yieldes relative gains, while the latter accountes on absolute gains in cooperative atmosphere. Also, Neoliberal Institutionalism, unlike Neorealism, believes that with the help of international institutions, one can gain international cooperation. The second step of this argument is structured around the competing views of "energy independence" and "energy interdependence" regardes. Then we apply this framework to Iranian oil and gas trade structure with current statistics to support the validity of cooperation from energy interdependence point of view.
