Under the United Nations Organization:
1. The world nations are not united but stand more divided in comparison to 1945, so UNO is a misnomer to begin with.
2. Infighting between the countries has escalated and more wars have been fought since its creation and UN has been unable to prevent or stop wars. Examples include India-Pakistan wars (1948, 1965, 1971 & 1999); Israeli wars against Palestine, Lebanon, Jordan, Syria, and Egypt (1948, 1956, 1967-70, 1973, 1982, 2006, 2008-09, 2014); Korean war (1950); Vietnam war (1954-75); Cambodian war (1967-75); Soviet-Afghan war (1979-89); Iraq-Kuwait war (1990); Iraq-Iran war (1980-88); US-Libyan war (2011); and US/NATO-Afghan war (2001-14) are just a few to mention.
3. Barring a few exceptions the UNO has not been able to enforce & implement its Resolutions to end armed conflicts of international significance. Examples of unfulfilled Security Council Resolutions include # 47 (Apr. 21, 1948) - Plebiscite in Kashmir; # 242 (Nov. 22, 1967) - Withdrawal of Israeli forces from occupied Arab territories; # 446 (Mar. 22, 1969) - Israeli settlements in Palestine are illegal; # 822 (Apr. 30, 1993) - Withdrawal of Armenian forces from Azerbaijan; # 1325 (Oct. 31, 2000) - Protection of women rights in international armed conflicts; # 1373 (Sep. 28, 2001) - Counter Terrorism; # 1397 (Mar. 12, 2002) - Reaffirmation of the Palestine State. Besides, General Assembly Resolution # 194 (Dec. 11, 1948) - Right of Palestinian refugees to return to their homes in Israel; # 3236 (Nov. 22, 1974) - Palestinians have a right to self determination are also examples of failure of UN to enforce its agenda.
4. The concept of five permanent members in the Security Council with veto powers has remained quite controversial throughout the UN history and against the principle of equality. In the 21st Century world we see no justification or validity for such exclusive status. All member states must have equal and similar rights and responsibilities irrespective of their geopolitical importance, strategic strength and economic conditions.
5. Economically and politically strong nations from amongst members states have openly violated UN resolutions and get away without any punitive action. No suspension, cancellation of membership or estoppel of other privileges is on record where violations have been taken seriously.
6. The mandate of UN agencies like UNESCO, UNICEF, UNDP, UNEP, UNIDO, UNODC etc is not pursued fairly and justly in under developed and developing nations of the world. The choice and priority of interventions of such agencies is politically driven, unevenly distributed, and have very high overhead costs. Recruitment of international staff is not transparent and remains heavily dominated by citizens of stronger nations.
7. It has no control over the US land where the UN headquarters and General Assembly are located. At times the USA restricts the participation of certain diplomats or heads of states because of political rivalry and that is totally against ethics of diplomacy.
8. Independent international organizations such as Permanent Court of Arbitration, Inter-Parliamentary Union, World Bank, World Trade Organization, International Criminal Police Organization etc have no justification. All such bodies should have been brought under the umbrella of UN.
In view of the above grounds the governments of the world and member states of regional organizations such as the European Union, Commonwealth, African Union, Organization of Islamic Countries, Arab League, South Asian Association for Regional Cooperation, Association of Southeast Asian Nations, Association of Caribbean States, Union of South American Nations are urged to seriously consider renaming and reconfiguration of the UN under modern principles of (i) equality among members, (ii) strict enforcement of human rights, (iii) fairness in dealing with member states without any political bias, (iv) equitable distribution of resources among poor nations for development, and (v) use of non-military options for conflict resolution.
