A scholar studying international law, as it is presented in the texts of international treaties and restatements of customary norms, could describe an ideal world. The United Nations Charter and other international instruments suggest a harmonious existence in which there is no use or threat of the use of force between States, where disarmament is complete, where international aid to developing countries enables them to satisfy the basic needs of their inhabitants, where international co-operation leads to social and cultural progress and where human rights are respected. Disputes over the application of rules of international law are settled by international tribunals or other peaceful means, and violations of law are sanctioned by the implementation of rules of State responsibility.
