'Amexit'

The United Nations as compared with other organizations is loosely organized. Although more idealistic proponents of the UN have thought it would be the salvation of humanity after a devastating world war and the threat of nuclear conflict, realists know that the UN was based upon the power of the Big Five - the five permanent members with veto power of the UN Security Council: the United States, Britain, France, China, and Russia.

Without the Big Five working to uphold key policies within the UN, the UN doesn't work. There are times it has not worked, and there are times it has on important issues. The General Assembly is simply to include less powerful countries to allow their voices to be heard, but it has little power beyond that. The idealists' vision of the UN unifying the world died the moment the Cold War escalated in 1948. This is not my opinion, it is the view of former US ambassador to the UN Adlai Stevenson and famous American diplomat Richard Holbrooke in a lecture.

International laws have existed and will continue to exist for the simple fact that there are treaties between multiple countries that have to understood by multiple parties, especially with international trade. Whether they are upheld by the UN or future completely different international organization of countries, these will continue. Also there are other activities that will continue to be undertaken by the UN or any future organization on matters of coordinating international aid. These are not necessarily done well - indeed corruption and nepotism problems are very real in the UN, and while the UN or a future organization could be reduced to minimal functions there regardless will be international laws that will need to continue.
