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.
Nuclear-weapon-free zone
The 6 Gulf Cooperation Council states, the 5 other Arab League states outside Africa (Yemen, Jordan, Lebanon, Syria, Iraq), and Iran (see Nuclear program of Iran) are not nuclear weapons states and not part of a NWFZ. The UN General Assembly has urged establishment of a Middle East NWFZ, and NPT Review Conferences in 1995 and 2010 called for a zone free of all weapons of mass destruction in the Middle East. An International Conference For A WMD-Free Middle East was held in Haifa in December 2013 attended by citizens from all over the world concerned about the lack of progress in the official talks.
