Astonishing, isn’t it? Beginning in July of 1945, with the
considerable assistance of Britain and Canada, the United States detonated a
19-kiloton fission bomb near Alamogordo, New Mexico. Directly following, near
the end of World War II, were the infamous detonations over Hiroshima and
Nagasaki.
2050 later, #2 and #3 remain the only detonations used in
directed belligerence; the remainder were weapons tests, engineering
experiments, or other scientific exploration. But mostly weapons tests.*
