The correct answer is - by blockading the island with aircraft carriers.
After Castro came to power in Cuba, he immediately made an alliance with the Soviet Union. That was a devastating news for the United States, as that meant that their arch rival will be able to make its basis right next door to their territory.
The United States responded by blocking the island as much as possible, by using numerous aircraft carriers that circled around the island, they were trying to threaten them, and also to be able to block or to respond quickly to any attack from Cuban territory.
I believe that would be Mesopotamia, the seat of the Sumerian and Akkadian civilizations.
