CEVAP:

According to realism, states are the major actors of international politics. Their interests and the rivalry for getting more powerful, shapes politics. Multinational companies (MNCs) and international organizations are not assumed as actors of international politics.

Realists accept states as rational actors; that behave in accordance with certain rules and national interests to realize their objectives and to sustain themselves through national capacity (Viotti and Kauppi, 1993: 35; Grieco, 1995: 153; Buzan, 1996: 54; Senarclens, 1991: 11-12).
