Explanation:

John F. Kennedy had this type of relationship with:

- Richard Nixon. Senator JFK (Democrat)  and vice president Nixon were rival candidates for the presidency in 1960. JFK won. Nixon would run again in 1968 and win.

- Martin Luther King Jr.  JFK was a supporter of civil rights and in this regard, he had a coincidence with MLK´s philosophy and goals. Dr. King supported Kennedy in his 1960 campaign. JFK´s brother Robert made calls to release Dr. King after his arrest during protests.

- Senator Joe McCarthy - Joseph Kennedy, president JFK´s father, was a friend of the famous senator Joseph McCarthy (both were of Irish famlies and shared similar anti-communist views). JFK and his brother Bob were also friends with McCarthy

- Fidel Castro. In 1961, with Kennedy´s approval, the CIA sent an invasion force made of Cuban exiles to get Castro out of power. It failed. The Cuban revolutionary leader gave revolution a radical turn, became an ally of the Soviet Union and an open US enemy. He allowed the USSR to install nuclear missiles in Cuba, but Kennedy got the missiles withdrawn from the island in 1962 following the October 1962 crisis.

- Nikita Khrushchev was the Soviet top leader that was involved in the October Missile Crisis in 1962 in Cuba. He faced the US warning, threat and naval blockade, but in the end he decided to de-escalate and withdrew the nuclear missiles from Cuba.

- Ngo Dinh Diem. He was a South Vietnamese president and had the support of the United States. He was Washington´s man in Vietnam for some years, until he was killed in a military coup that led to another government.
