Set of related theories of international relations that emphasizes the role of the state, national interest, and power in world politics

The set of related theories of international relations that emphasizes the role of the state, national interest, and military or economic power in world politics is known as Realism.

Here are the steps to understand this:

1. Realism is a school of thought in international relations theory, which asserts that states are primarily driven by the competitive pursuit of their own national interests and not by ideals or ethics.

2. Realists believe that nation-states are the main actors in international politics and that the primary concern of all states is their own security.

3. In this view, conflict and competition between states is inevitable because states will always act in their own interest, even at the expense of others.

4. Realism also emphasizes the distribution of power in international relations. It is often divided into two main branches: classical realism, which argues that power is inherently a part of human nature, and neorealism, which suggests that the international system itself encourages states to pursue power.

5. Realists often use historical cases and empirical data to support their theories, arguing that history shows that realism offers the most accurate explanation of international relations.

6. Despite its pessimistic view of international politics, realism is one of the leading and most enduring paradigms in the field of international relations.
