The U.S using nuclear weapons to end World War II.

Explanation:

The arms race went hand in hand with the Cold War, which took place 20 or so years after World War II. It was a tense situation and resulted in the U.S. and Russia stockpiling nuclear weapons as a means of protection. When America used two atomic bombs on Japan, the devastation it caused led other countries to be concerned if they were going to be next.
