Answer:
Nations constantly establish diplomatic relations with each other. Many nations, due to their relations of collaboration and cooperation, are allied with others. This means that they share a series of common interests, which align them on the international stage.
For a nation to decide to establish an allied relationship with another, it must interpret possible future benefits as a result of that alliance. These alliances are created based on trade, military, and even ideological relations, and serve to make these nations develop their common interests among themselves.
