The arms race during the Cold War refers to the competition between the United States and the Soviet Union to build up their military power with nuclear weapons. This competition created a state of heightened tension and suspicion between the two superpowers, as each side sought to outdo the other in terms of military capability. This arms race also led to an increased risk of accidental nuclear war, as both sides had large amounts of weaponry on high alert and ready to be used at a moment's notice. Overall, the arms race was a major factor in the increased tension and uncertainty of the Cold War period.
