In 1962, how did the united nations prevent a missile crisis from becoming a nuclear war?
a) the un negotiate a treaty between the united states and argentina
b) the un used its military to raid suspected communist countries for nuclear weapons.
c) the un held a trial against saddam hussain for violating the declaration of human rights.
d) the un negotiate peace between nikita khrushchev and john kennedy during the cuban missile crisis.

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 

Ithink the answer is b.)
