Answer: The repetition is used to show unity among all people in the United States, which helps advance Kennedy's overall purpose.
Step-by-step explanation:
Dr. Martin Luther King, Jr. was a reverend and activist in the fight for the civil rights of African-Americans. He was killed on April 4, 1968, in Tennessee by a sniper when he was gathered with some followers.
Dr. King's death led to several riots throughout the country, which is why President Kennedy in his speech tries to call the union of the country by using the pronoun "we" repeatedly, including himself in that union.
