How many times could the same ceramic dish be shattered?

However, you might have been thinking of the principle of overkill, that the nuclear arsenals of the world contain more weapons than would be needed to destroy the entire world. At a rough guess, the total inventory of nuclear weapons in the world is sufficient to destroy a dozen worlds at least (if we had a means of getting to other worlds, of course). But the Earth can be destroyed only once.

In the most basic sense, proliferation of nuclear weapons is the spread of nuclear weapons and weapons usable technology in the world. In a much broader sense, it refers to the acquiring of capability to produce nuclear weapons, or weapons-grade nuclear material (high-enriched uranium, plutonium) by states previously not possessing them.
Yes, by a small amount, placing them in strategic locations that would make the earth's crust break up and covering the planet in lava
