What resulted from a 1961 conference in vienna between president john f. kennedy in nikita khrushchev

The summit did not resulted in a positive outcome, instead it started a whole new Cold War game on June 3.4. 1961.

On the one hand, Nikita Khrushchev took harsh position over Berlin, a Western spot within communist-controlled East Germany. On the other hand, in that summit Kennedy made it clear that he was not willing to withdraw from Berlin. As a result, there was not progress in the negotiations. However, according to Nikita´s words, in that summit, “Kennedy held a stance through which he was willing to find a peaceful solution to world problems and avoiding conflict with the Soviet Union.”

Following the Summit, the Berlin wall was erected two months later and the Cuban Missile Crisis led the world to the verge of nuclear war in 1962.
