The most important achievement of international law is the principle of the prohibition of the use of force by States in their international relations. Only this Organisation is entitled to make use of force - within the limits provided in the Charter - except with the exception of the provisional authorisation granted to States in case of self-defence. It is by the application of this system and by the observance of other fundamental principles of contemporary international law - and as the right of peoples to self-determination, the principle of non-intervention; and the sovereign equality of States - that the existence of all States and dele . against aggression are ensured.
