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.
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.
