The UN is going bankrupt because it's members aren't paying their dues.You are mistaken.
International law, specifically Article 51 of the UN Charter, recognizes an inherent right to self-defense if an armed attack occurs. While Article 51 strictly mentions an actual attack, it is widely accepted that anticipatory self-defense is permitted against an "imminent" (immediate/inevitable) attack, though "preventive" strikes against mere future threats are prohibited
The UN should be disbanded because they are terrorist supporters and corrupt to the core.
