The two post-Korean War American foreign policy crises/conflicts were the following:
The Cuban Missile Crisis and the US intervention in the Vietnam War.
The role the “Cold War Lens” had in forcing an American response was the permanent interest or top priority United States foreign policy of containment.
That policy of containment was implemented to stop the spread of Communism around the world.
Through the policy of containment, the United States could prevent the domino effect, and limit the expansion of Communism in different places.
Let's have in mind that during the Cold War years, the Soviet Union tried to spread Communism in different countries of the world, meanwhile, the United States tried to stop it.
The Cuban Missile Crisis and the US intervention in the Vietnam War were two international conflicts that made the US federal government intervene in order to protect its interests and contain Russia Communism.
We conclude that during the Cold War years, the US and the USSR had many differences and exchanged accusations that put the world on the brink of another world war.
That was was the case of the Cuban Missile Crisis of October 1962.
They also competed in the arms race and the space race.
