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.
Iran and weapons of mass destruction
Iran states it has a legal right to enrich uranium for peaceful purposes under the NPT, and further says that it "has constantly complied with its obligations under the NPT and the Statute of the International Atomic Energy Agency". Twelve other countries are known to operate uranium enrichment facilities. Iran states that "the failure of certain Nuclear- Weapon States to fulfill their international obligations continue to be a source of threat for the international community". Iran also states that "the only country that has ever used nuclear weapons still maintains a sizable arsenal of thousands of nuclear warheads" and calls for a stop to the transfer of technology to non-NPT states. Iran has called for the development of a follow-up committee to ensure compliance with global nuclear disarmanent. Iran and many other nations without nuclear weapons have said that the present situation whereby Nuclear Weapon States monopolise the right to possess nuclear weapons is "highly discriminatory", and they have pushed for steps to accelerate the process of nuclear disarmament.
