Weapon of mass destruction
The only country to have used a nuclear weapon in war is the United States, which dropped two atomic bombs on the Japanese cities of Hiroshima and Nagasaki during World War II. There are eight countries that have declared they possess nuclear weapons and are known to have tested a nuclear weapon, only five of which are members of the NPT. The eight are China, France, India, North Korea, Pakistan, Russia, the United Kingdom, and the United States.
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).
