This history of the United Nations recounts the actions of the UN in confronting the world's crisis situations, the conflicting policies of the member states and the initiatives undertaken in each case to preserve the peace. It is based on detailed examination of the record UN discussions. This volume deals with a period when the organization was involved with major crises over Suez, Hungary, Lebanon, India, the Congo, the Cuba Missile Crisis and armed conflicts in Cyprus, Kashmir and the Dominican Republic. It covers the first UN peace-keeping operations: in Sinai, the Congo and Cyprus. It examines the effectiveness of the UN's peace-keeping role in these countries and suggests how this might be improved.
