Do the math

Castro will continue with executions as a way of eliminating those that oppose him and his failed revolution. In a 44 years period castro has executed 11.4 persons based on a monthly average.

The Cuban government does not publish statistics on the country’s prison population, individuals sentenced to death, or executions. Nevertheless, Sánchez asserts that between 5,000 and 6,000 people were executed in Cuba between 1959 and 2003, "most of them for so-called crimes against the state or offences with political connotations." Link to story.

In comparison the United States has executed and average of 2.8 persons per month over 30 years (since 1976). Therefore, it will take the United States 179 years to reach the same number of executions that Cuba has achieved in 44 years. Consideration should be given that Cuba's population is less than 4% that of the US.
