How Every Country Got Nuclear Weapons

In 1949, radioactive debris collected over the North Pacific revealed that America’s nuclear monopoly was over. Follow how the race spread to nine nuclear-armed states—and why South Africa built six devices, then dismantled them. This original documentary follows the United States, Soviet Union/Russia, Britain, France, China, Israel, India, Pakistan and North Korea, then separates inherited Soviet weapons from South Africa’s former arsenal. First tests, weapon possession and treaty categories are different milestones. Israel is not assigned a verified first-test date. Which mattered more: fear of an enemy, or distrust of an ally?
