Reading the posts concerning the UN, they appear all aimed at the UN Security Council, and it’s decline in relevance over the years, largely as a result of the widening ideological block, and increasing power between China/Russia and supporters v USA/Europe and supports.
The result is that the 5 veto bearing members - USA, Russia, U.K. France and China use their veto to prevent so many decisions being carried through. So if it’s primary purpose, is still to maintain world peace, then the UN has spectacularly failed.
But without doubt the UN has been successful in a number of areas - sustainable development goals is one that is working well, and the feeding and vaccination programmes have saved countless lives - I am sure that those who have benefited from its administrations do not think it is irrelevant. The climate change forum needs an agency at supranational level and the UN has provided valuable service in this area. The WHO has also been invaluable. The ICJ is another major success. The IMF - invaluable, ICAO - invaluable and vital. So many others which we forget about.
I do, however think that there is an urgent case however to look at the clear slowness and inefficiency, the need to have a much higher level of housekeeping and clear out corruption and cronyism (where have we heard that before?)- it certainly needs a root and branch overhaul.
But before we become gung-Ho demanding it’s sacking, we must think very carefully about what we are trashing. In my view if the UN didn’t exist it would have to be invented.
