Quizplus · Accepted Answer

Idealism and realism are two of the most prominent theoretical traditions in international politics because they represent fundamentally opposing views on how states should interact in the international system, the nature of international relations, and the key drivers behind state behavior. Idealism emphasizes the role of international law, moral principles, and international organizations in promoting peace and cooperation, while realism focuses on the anarchic nature of the international system and argues that states primarily act out of self-interest and the pursuit of power.
