Real Politik in international relations is best described as a philosophy where international peace and security is achieved by self-interested states being prepared for war. This approach is based on practical considerations rather than ideological or moral ones. It involves a state pursuing its own interests, sometimes aggressively, to maintain its security and power.

Here's a step-by-step breakdown:

1. Real Politik is a German term that translates to "realistic politics". It is a philosophy of politics that is based on practical and material factors, rather than on theoretical or ethical objectives.

2. In the context of international relations, Real Politik involves states making decisions and taking actions that are in their own best interests. This could involve a range of actions, from diplomatic negotiations to military interventions.

3. One of the key aspects of Real Politik is the idea that states must always be prepared for war. This doesn't necessarily mean that they are always seeking to start wars, but rather that they must always be ready to defend themselves and their interests.

4. This approach to international relations is often contrasted with more idealistic or moralistic approaches, which argue that international peace and security can be achieved through cooperation, diplomacy, and the promotion of shared values and interests.

5. Therefore, the statement "International Peace and security is achieved by self-interested states being prepared for war" best describes Real Politik in international relations.
