I discovered this on Information Dissemination. This is a movie of all the atomic/thermonuclear tests that went on during the Cold War and into the 1990s. It is a fascinating way to understand just how many tests/explosions were detonated. Please have a look, it is worth the time.
Here are a few things that are of interest to me:
1. The obvious alliance between Britain and the US...check out those later British tests.
2. The French and the way their tests seem to go unimpaired by treaties from the 1980s to 1990s.
3. Just HOW MANY were conducted in the US.
4. The Israelis apparently have never tested a nuclear device (I am under the impression they have nuclear weapons [correct me if I am wrong]).
5. The Soviet Union's SLOW beginning, where as the US conducted tests of multiple devices during a short period early on, the Soviets appeared to do one at a time.
Enjoy and let me know what YOU think!
