On more than 30 occasions, the United Nations Assembly has discussed the blockade against Cuba, which costs the island 5 billion dollars annually, according to some estimates. Every year the resolution is proposed and the whole world, through the vote of the absolute majority of the member countries of the United Nations General Assembly, has condemned the imperialist attitude of the United States towards Cuba.

ALL of international politics is ruled by those with the biggest guns! There is no mommy or daddy to make the kids play nicely.
The UN is an attempt to allow for international discussions, collaboration and some sense of “law”. It is and always will be flawed, but that doesn’t mean its useless.
