1. Who offers a more convincing stance on the role of morality in international politics? Liberals or realists?

Realism offers a more convincing stance on the role of morals within international politics as it recognises that the anarchical state of international politics is immutable as long as sovereign states exist. Maintaining the balance of power, which may involve concessions or gains in the form of limited conflict in peripheries, is perhaps even more moral when observed holistically.

and the European Union

Interest-based theories of International Relations view the European Union as a functional supranational body and an actor in Global Politics. According to the interest-based view, through the institution of certain procedures and standards such as in many laws, and cooperation throughout a multitude of areas such as the economy, environment and security, international organisations like the European Union can help bring prosperity to countries and help advance their mutual interests. Many different liberal institutionalist theories of International Relations provide different explanations of how and why countries cooperate. Interest-based theories argue that as countries aim to make decisions which advance many interests, not just power, those same countries will be drawn to cooperate as that is more beneficial.
