Freedom in international relations refers to the idea that individuals, states, and other actors in the international system should be able to act and make decisions free from coercion, interference, or domination by others. Freedom can take many forms, including political freedom, economic freedom, and freedom of speech and expression. In international relations, freedom is often seen as an ideal that should be upheld and defended, and it is often used as a justification for action in the international arena.
