The Cold War was a decades-long struggle for global supremacy that pitted the capitalist United States against the communist Soviet Union. Although there are some disagreements as to when the Cold War began, it is generally conceded that mid- to late-1945 marks the time when relations between Moscow and Washington began deteriorating. This deterioration ignited the early Cold War and set the stage for a dynamic struggle that often assumed mythological overtones of good versus evil.
By 1960, both sides had invested huge amounts of money in nuclear weapons, both as an attempt to maintain parity with each other's stockpiles, but also because the idea of deterring conflict through "mutually assured destruction" had come to be regarded as vital to the national interest of both. As nuclear weapons became more prolific, both nations sought to position missile systems in ever closer proximity to each other's borders. One such attempt by the Soviet government in 1962 precipitated the Cuban Missile Crisis, arguably the closest that the world has ever come to a large-scale nuclear exchange between two countries.
It was also in the early 1960s that American containment policy shifted from heavy reliance on nuclear weapons to more conventional notions of warfare in pursuit of a more "flexible response" to the spread of communism. Although originally articulated by President Kennedy, it was in 1965 that President Johnson showcased the idea of flexible response when he made the initial decision to commit American combat troops to South Vietnam. American thinking had come to regard Southeast Asia as vital to its national security, and President Johnson made clear his intention to insure South Vietnam's territorial and political integrity "whatever the cost or whatever the challenge."
