Abstract
2001 saw the world united in indignation, and the emergence of a tacit promise to cooperate in the war to annihilate the flaw of terrorism. 2002 saw the same world divided and torn in the debate over a war carried out by those considering it as vital, and opposed as inconsiderate and unwise by others, in the process placing at risk the legitimacy of the greatest international institution, bringing forth once more the ancient realist assumption that international politics is ruled by power.
The stark opposition between these two events throws into light the question that has animated the debate in international relations for the past centuries: Is cooperation possible in the international context?
To tackle this question, we shall first oppose the Realist view that cooperation is fundamentally undesirable to the liberal "Utopianist" view that cooperation is the only proper way for the international system to function. Then we shall move to what has been known as the "neo-neo" debate, observe how this synthetic approach tackles the problem of cooperation and confront these modern theories to the twenty-first century international reality to measure how cooperation fits into our globalized world.
There has been for centuries a large debate between different schools of international relations as to whether cooperation between nations is possible or not. The most universally accepted and long standing theory that has emerged from this debate is what is known as "Realism". After having analyzed the theoretical and philosophical basis of this theory, we shall seek to understand what this implies in terms of cooperation among nations and find its flaws concerning its analysis of cooperation. The realist theory finds its fundamental basis in its idea of human nature. It was Thucydides in his analysis of the Peneloponesean war who first described his low esteem for human nature and behavior. According to him, men are selfish, act under the domination of passions, guided by a thirst for prestige. This has for consequence that "the strong do as they may, the weak suffer what they must." This makes the law of the strongest the law of all in the international system, and all politics are based on this assumption. For realists, self interest is the only relevant incentive to action in the international system. This is the translation of the selfish nature of humanity in terms of states. These interests are usually summed up to the quest for power, referred to as "capabilities" and survival. These two interests are distinct, according to the realist theoretician Morgenthau, in his "Politics among Nations" because for him power keeps shifting and is not stationary. It is not always held by the same states, and not always in the same proportions, contrarily to the notion of self interest, which is defended at all times by all states. Concerning morality, realists do not believe that states have any moral considerations while acting, and that there are no universal moral laws which regulate the international system.
