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.

Oh definitely, they can’t all be deployed at once - but the ability to rotate them out means a sustained presence that nobody else can achieve. And the point is really more about the organization structure that supports those carriers and their accompanying battle groups - the US can control any part of the ocean anywhere in the world, for as long as they want. That kind of force projection is hard to compete with.
