Though the UN has failed in preventing wars and related miseries, nations prefer its continuation because without it the world would be worse off.

• There is requirement for an international body which keeps a watch over myriad activities going on over the world so that no one nation dominates over others.

• The UN makes interdependence and globalisation possible. The World Trade Organisation makes global trade possible and regulates it for free and fair trade.

• Technology is increasing planetary interdependence which makes the need for UN even more.

• The international Monetary Fund and the World Bank are organisations that help various new and developing economies of the world to grow and also prevent economic crises by maintaining economy of the world.

• UNICEF, UNESCO, WHO, UNDP etc are all international UN organisations made for humanitarian activities and are the need of the hour for the world.

• The UN works as a forum where nations can put up their disputes which can be resolved in the best way possible.

Hence, despite failing to prevent wars and related miseries, the world is in dire need of UN.
