Here you have your basic Nuclear Detonation timeline from recognized “Nuclear Weapon States.”

As the video starts out detonations are few and far between. The first three detonations represent the Manhattan Project and the two bombs that ended World War II. After a few representative minutes the USSR and Britain enter the nuclear club and the testing really starts to heat up.

Even though the video does not differentiate between sub-critical “safety” tests and full detonations, you get a good idea of the fever of the nuclear arms race.

Sleep well.
