Answer:
Both speeches use pathos as a similar rhetorical choice.
Step-by-step explanation:
Both speeches make a strong appeal to pathos, which is the rhetorical resource that stimulates the emotional side of the audience that is listening to the speech, making them touched by the arguments presented.
However, each speech makes an appeal to emotion with different arguments. Nixon's speech makes an appeal to American pride, showing that the ceasefire in Vietnam will be an honorable act, in favor of the pride of American society. On the other hand, King's speech is focused on compassion towards the Vietnamese who have had their lives, families and home destroyed because of the war.
