Nuclear weapon
Since the atomic bombings of Hiroshima and Nagasaki, nuclear weapons have been detonated over two thousand times for testing and demonstration. Only a few nations possess such weapons or are suspected of seeking them. The only countries known to have detonated nuclear weapons—and acknowledge possessing them—are (chronologically by date of first test) the United States, the Soviet Union (succeeded as a nuclear power by Russia), the United Kingdom, France, China, India, Pakistan, and North Korea. Israel is believed to possess nuclear weapons, though, in a policy of deliberate ambiguity, it does not acknowledge having them. Germany, Italy, Turkey, Belgium and the Netherlands are nuclear weapons sharing states. South Africa is the only country to have independently developed and then renounced and dismantled its nuclear weapons.
Public opinion on nuclear issues
In 2013, Soka Gakkai International released the results of its international survey in which 91.2% of respondents believe that nuclear arms are inhumane and 80.6% favor a comprehensive treaty banning all weapons of mass destruction. The 2,840 survey respondents were men and women of ages 15 to 45 from Australia, Brazil, Britain, Italy, Japan, Malaysia, Mexico, South Korea and the USA—the official and unofficial nuclear weapon states, states under the US nuclear umbrella and states in nuclear-weapons-free zones (NWFZs).
