~ This captures the reality of 50+ years of nuclear weapons development, and its spread to a growing number of countries.
It is a shame that it ends in 1998 rather than going through the present day, but the graphic is dependent on the data source (described at the end of the video.) It does include the tests by both India and Pakistan, as well as the "traditional" nuclear powers, the US, Russia, the UK, France, and China (not coincidentally the 5 permanent members of the UN Security Council.) The data also does not include any indication that Israel has a nuclear capability, although that is widely considered certain.
Skip forward to about 12:10 to see a two minute summary by country.
Some interesting data (from 1998) on the US nuclear weapons program:
- Through 1990 the US built more than 70,000 warheads of 65 different kinds
- Land area used for nuclear weapons and facilities is larger than that of DC, Massachusetts and New Jersey combined
- There are more than 75 secret Presidential Emergency Centers for use during and after a nuclear war
- There is 104 million cubic meters of high level nuclear waste
- 11 nuclear weapons have been lost in accidents and never recovered
