When did the “Nuclear Age” dawn and how long did it take to negotiate an international norm against all nuclear testing?

The “Nuclear Age” dawned with the first nuclear test carried out by the United States of America on 16 July 1945 at Alamogordo, New Mexico. Less than a month later, it dropped two atomic bombs on Japan – on Hiroshima on 6 August and on Nagasaki on 9 August 1945. Japan surrendered on 15 August 1945, bringing an end to World War II. However, nuclear testing did not end. On the contrary, it took five more decades—until the 1996 adoption of the Comprehensive Nuclear-Test-Ban Treaty—until efforts to “put the nuclear genie back in the bottle” really began to bear fruit.
