The crisis also led to a growing awareness of the need to create some control over the nuclear arms race as it was evident that the arms race brought nothing but immense negative pressure to world security. The Nuclear Test Ban treaty was signed in 1963, which banned the testing of nuclear weapons above ground and under water. It was a measure of the desire to limit nuclear destruction after the Cuban Missile Crisis. Furthermore, in 1968, the Nuclear Non-Proliferation Treaty, which was designed to prevent the spread of nuclear weapons to other countries, was also signed by USA and USSR, which, emphasizes the willingness of both nations to peacefully resolve their differences. These agreements were encouraged by the changes that occurred in public opinion as seen from the growth in support for groups campaigning for peace and nuclear disarmament in countries such as USA and West Germany. All these evidence shows that the containment policy was a failure as it highlights the efforts both nations put into maintaining a peaceful dual existence instead of containing communism like USA previously did.
The failure of the containment policy is further exemplified through USA’s failure of abiding to the Monroe Doctrine of 1823, stating, “Further efforts by European nations to colonize land or interfere with states in North or South America would be viewed as acts of aggression requiring U.S. intervention.” Soviet Union’s act of placing missiles in Cuba showed the failure of the containment policy as USA failed to prevent it from happening in the first place, which highlights the flaws of the containment policy. Furthermore, the end of the crisis saw Cuba remaining as a communist state, which was a direct evidence of USA’s failure despite the immense pressure they put on Soviet Union.
In the long term, despite the moves towards détente and controls over nuclear testing, the USSR emerged from the crisis with a determination to restore its international status. This was due to the massive humiliation USSR felt upon withdrawing the missiles in Cuba after USA’s threat. The Soviet Union had been forced to respond rather than being deterred from taking action and ultimately led to a “defeat” for the Soviet Union, as there was a constraint on Soviet freedom of action in the international arena. This affected USSR’s national pride and the policy of containment backfired as instead of limiting the spread of world communism, it gave USSR a reason to bounce back from its humiliation and restore its international status, as evident in USSR’s invasion of Afghanistan in 1979.
Despite USA’s strategy of containment evidently failing, the immense pressure USA put on USSR could also be seen as a positive outcome as it shited and moved the bipolar world closer towards greater cooperation prior to the era of détente which was to follow. One can argue that this was containment in a way as it stalled soviet aggression through peaceful means. USA also led to a souring Sino-soviet relationship due to Khruschev’s failure of keeping the missiles in Cuba, which could have positively hindered the growth of communism.
In conclusion, I believe following the Cuban Missile Crisis, both superpowers and the world saw a greater need for peaceful coexistence as they were on the brink of a very destructive nuclear war. Although it is dubious that they genuinely wanted it, attempts for a dual existence of opposing ideologies is evident and both superpowers felt that peaceful coexistence was necessary at that point of time, therefore, rendering the policy of containment an ultimate failure.
