I believe the answer would be D. The UN helped negotiate peace between Nikita Khrushchev and John Kennedy during the Cuban Missile Crisis. That should be the answer since the Cuban Missile Crisis was during the Cold War which at the time John F. Kennedy was the current president at that moment in time and Nikita Khrushchev was in power of Russia. The cold war was a war that didn't involve any bloodshed at all it was just fear since both sides of the war had nuclear missiles aimed at each other. This you will learn about later on, but for now have a nice day
