Cuba-US relation once again becomes a news headline. I found an interesting fact about term length for presidency on W|A about the leaders in the two countries.
W|A has a very cool and standard-Instagram-selfie-style portrait for Fidel Castro

Besides the image data, W|A gives a data table about duration of him serving Cuba as a high rank officer

Castro has been the first chair of the Communist Party of Cuba from 1965.
during which time the people in US have had seen 9 presidents. From:
