The Secret War in Central America and the Future of World Order
The core principle of modern world order is that aggressive attack is prohibited in international relations and that necessary and proportional force may be used in response to such an attack. This dual principle is embodied in Articles 2(4) and 51 of the United Nations Charter, Articles 21 and 22 of the revised Charter of the Organization of American States (OAS) and virtually every modern normative statement about the use of force in international relations. Indeed, it is the most important principle to emerge in more than two thousand years of human thought about the prevention of war. In the contemporary world of conflicting ideologies and nuclear threat, no task is more important for international lawyers and statesmen than to maintain the integrity of this principle in both its critical—and reciprocal—dimensions: prohibition of aggression and maintenance of the right of effective defense.
