The United Nations Organisation (UNO) which was formed on 24th October 1945 after the Second World War ( 1942-45) by 51 countries ‘committed to maintaining international peace and security, developing friendly relations among nations and promoting social progress, better living standards and human rights’ is completing 57 years of service. At present there are 193 member countries in the UNO. The UN has intervened on many occasions to bring down conflicts and restore peace among countries. But in the last few decades after the collapse of the USSR, it is almost being controlled by the US and many decisions are becoming partisan. However, its contribution in the past has been of great help to many nations. Let us hope that UNO functions effectively to bring world peace.
