(Inside Science) — There are enough nuclear weapons in the world to cause atomic Armageddon many times over, according to scientists, who estimate that no country could fire more than 100 nuclear warheads without wreaking such devastation that their own citizens back home would be killed.

Most nuclear nations recognized by the Treaty on the Non-Proliferation of Nuclear Weapons — namely, France, Russia, the United Kingdom and the United States — have set about reducing their arsenals. China is a notable exception. The exact number of the country’s warheads is unknown, but many analysts say its cache is slowly growing in size. North Korea, on the other hand, while notoriously difficult to predict, could eventually scale back its nuclear program if its diplomatic rapprochement with the West continues.

Negotiations on nuclear disarmament are politically tricky. But when agreements are reached, scientists and engineers can provide a variety of tools to take apart some of humanity’s most deadly weapons and store or repurpose the dangerous nuclear material. It’s a long and complex procedure, but experts say it’s one worth doing.
