Which nation held the edge in the arms race until the late 1960s?

Answer 1

The United States held the edge in the arms race until the late 1960s, primarily due to its significant advancements in nuclear weapons technology and delivery systems. The U.S. developed a substantial stockpile of nuclear warheads and intercontinental ballistic missiles (ICBMs), which provided a strategic advantage. However, this dynamic began to shift as the Soviet Union made significant strides in its own nuclear capabilities, culminating in the development of their own ICBMs and a growing arsenal, leading to a more balanced nuclear standoff.
