In the twentieth century, and particularly under the influence of the Second World War, the international community, in the interests of normal relations, has considered it necessary to agree on certain fundamental principles, such as the observance of universal human rights, the right of nations to self-determination, the equality of the rights of big and small nations, impermissibility of aggression, and liberation from the yoke of colonialism. These principles are written in international conventions, the UN charter and several of its resolutions, and recognized by the majority of states.
