Answer:
Obama, J.F. Kennedy
Explanation:
After more than four decades, President Obama restored the American diplomatic ties with Cuba that were severed by President J.F. Kennedy.
In 1961, President J.F. Kennedy severed diplomatic ties with Cuba after President Fidel Castro of Cuba expropriated United States assets in Cuba and developed close links with the Soviet Union. During the tenure of President Barack Obama, he mended diplomatic ties with Cuba by ending the trade embargo with Cuba and removing restriction of travel between Cuba and America. By December 17, 2014, President Obama and President Raul Castro announced the beginning of measures to mend diplomatic ties between America and Cuba and on March 2016, President Obama visited Cuba.
