In the international system and law, states are in the utmost position by virtue of their sovereignty. The structure and the balance of international relations have a dynamic character that evolves with the acts, relations, and inventions of the states. This creates an anarchic order in which states behave in accordance with their interests which always comes within the need for survival in the system. This system has such a structure that it prepares the basis for actors to work in cooperation as well as to conflict with each other. After the World Wars, exhausted states reverberated their need for survival via creating international organizations.
