The correct answer to this open question is the following.
Although the question does not provide any reference to the kind of meeting it is talking about or any reference at all, we can say that it refers to the Cuban Missile Crisis of October 1962. Robert Kennedy had meetings with USSR leaders to negotiate and avoid what was imminently coming, a war confrontation between the two superpowers. I think Robert Kennedy felt tense and nervous during the meeting because he had told Russian leader Khrushchev that the United States would slowly remove its missiles in Turkey, if the Soviet Union would remove its missiles from the Island of Cuba, that is 90 miles south the Florida peninsula. Those were tense and critic moments in which the world was on the brink of another world war.
