I'm not well read on this subject, but I thought it was interesting. It isn't binding, being a recommendation, but it is an alternative to disbanding the UN perhaps. I haven't tried to gauge support for such a thing at the General Assembly either.
United Nations General Assembly (UNGA) resolution 377 A,[1] the "Uniting for Peace" resolution
https://en.wikipedia.org/wiki/United_Nations_General_Assembly_Resolution_377From the article:
United Nations General Assembly (UNGA) resolution 377 A,[1] the "Uniting for Peace" resolution, states that in any cases where the Security Council, because of a lack of unanimity among its five permanent members (P5), fails to act as required to maintain international peace and security, the General Assembly shall consider the matter immediately and may issue appropriate recommendations to UN members for collective measures, including the use of armed force when necessary, in order to maintain or restore international peace and security. It was adopted 3 November 1950, after fourteen days of Assembly discussions, by a vote of 52 to 5, with 2 abstentions.[2] The resolution was designed to provide the UN with an alternative avenue for action when at least one P5 member is using its veto to obstruct the Security Council from carrying out its functions mandated by the UN Charter.
