The UN in theory maybe. But an institution that allows an illegal trade embargo to continue 33 years in a row (longer before votes on it even began) because "special vetos" are more important than human rights. Yeah. Fuck that.
Like, the idea of what a "United nations" might be in the average westerners head. Sure. But, that's not what the UN is at all. The UN exists to create a hierarchy that exists to uphold the American empire and it's capital interest. So, I'd start over from the drawing board.
Edit: Cuba trade embargo if it wasn't obvious.
