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.
Criticism of United States foreign policy
The U.S. is advocating that Iran and North Korea should not develop nuclear weapons, while the U.S., the only country to have used nuclear weapons in warfare, maintains a nuclear arsenal of 5,113 warheads. However, this double standard is legitimated by the Nuclear Non-Proliferation Treaty (NPT), to which Iran is a party.
