The correct answer to this open question is the following.
A news segment that would have aired during the Cold War on TV could have been the tense moments during the Cuban Missile crisis.
During 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. The media news reported that 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.
The media coverage said that those were tense and critical moments in which the world was on the brink of another world war.
