How did the Cold War affect nuclear weapons?
During the Cold War the United States maintained a “triad” of ICBMs, SLBMs, and heavy bombers in a strategic nuclear arsenal of more than 10,000 warheads. During the 1990s, the United States reduced the size of this arsenal to around 7,000 warheads , but maintained all three legs of the triad.
