Answer: a. The creation of the space race in response to Sputnik
Step-by-step explanation:
a. The creation of the space race in response to Sputnik was not a diplomatic issue during the presidency of John F. Kennedy.
The other options were all diplomatic issues during Kennedy's presidency:
b. War between Israel and her Arab neighbors: Kennedy had to deal with the tense situation in the Middle East and the possibility of war between Israel and her Arab neighbors, including during the 1961 crisis over the Eilat blockade by Egypt.
c. The Bay of Pigs invasion: This was a failed CIA-sponsored military invasion of Cuba by Cuban exiles in April 1961, which Kennedy approved, but which ended in a humiliating defeat.
d. The Cuban Missile Crisis: This was a major diplomatic crisis in October 1962, when the United States discovered that the Soviet Union had placed nuclear missiles in Cuba, which could potentially threaten the security of the US. Kennedy's handling of the crisis is considered a key moment of his presidency.
