1953 Doomsday Clock Time: 2 Minutes To Midnight
In 1953 the doomsday clock is set forward one minute to 2 minutes to midnight. By 1953, the United States begins developing the hydrogen bomb, more destructive than the atomic bomb.
The United States tests their nuclear weapon on a small island in the Pacific called Bikini Atoll, completely destroying it. Russia develops its own hydrogen bomb less than a year later.
