What was the 'arms race' of the 1950's between the superpowers?

The arms race of the 1950s was a tense competition primarily between the United States and the Soviet Union to develop and stockpile nuclear weapons and advanced military technology. Following World War II, both nations sought to establish military superiority, leading to the proliferation of nuclear arsenals and the development of intercontinental ballistic missiles (ICBMs). This period was characterized by significant investments in defense, espionage, and technological innovation, contributing to the Cold War's atmosphere of mutual distrust and fear of nuclear conflict. The arms race ultimately heightened global tensions and shaped international relations for decades.
