50 years ago there were more nuclear weapons ready to be used then there are now. What has changed? Will the number of nuclear weapons ready to be used continue dropping until zero? It"s very unlikely.
Anybody can study astronomy and gather enough information about physics to help build a bomb, but nobody does.
The trend toward less 'nuclear capable radicals', fewer dangerous people with nukes, is not sustainable. Either an effort has to be made to reduce basic education, reading and writing, or 'govts', have to civilize in such a way that nuclear use is less attractive to small groups.
I don't know exact number of nuclear weapon 50 years ago, but in time people understood devastating power of nuclear weapon, and if its used massively what would it do to earth. People want power, and they tend to make nuclear bombs to show that "power" to other people. But it could come to nuclear war, we just need one fool to start it.
