ICAN has been the main civil society player that has worked with governments to achieve a strong and effective prohibition treaty.  The International Red Cross and Red Crescent Movement has also called for an agreement on the prohibition and elimination of nuclear weapons, and the UN working group`s recommendation to negotiate a ban in 2017 is described as “potentially historic”.  Thousands of scientists around the world have signed an open letter in support of the negotiations.  The treaty does not specify which “competent international authority” would be likely to verify the irreversible disarmament of an armed nuclear state that decides to accede to the treaty, but it does allow for the subsequent designation of an appropriate authority. The treaty requires any current or former nuclear state wishing to join the Prohibition Treaty to enter into a safeguards agreement with the IAEA to verify that nuclear materials are not diverted from peaceful nuclear materials for weapons purposes. When it joins the treaty, a state party must declare whether it has abolished an old nuclear weapons programme, whether it currently has nuclear weapons, or whether it has another country`s nuclear weapons on its territory. If one state has another country`s nuclear weapons on its territory, if it signs the treaty, it must withdraw them. If it has its own nuclear weapons, it must eliminate them. At the time of the proposal of the Non-Proliferation State and nuclear weapons, it was within 20 years. Instead, more than forty years later, five states are not parties to the non-proliferation treaty, and they include the other four states that are presumed to possess nuclear weapons.
 Several additional measures have been taken to strengthen the NPT and the broader nuclear non-proliferation system and to prevent States from acquiring the capability to manufacture nuclear weapons, including export controls of the Nuclear Weapons Supplier Group and enhanced review measures of the International Atomic Energy Agency (IAEA) Additional Protocol. Article 2 requires each party to declare whether it has its own nuclear weapons or is being used on its territory, including the disposal or transformation of related facilities. 8-9 December 2014: A third conference on the humanitarian impact of nuclear weapons will be held in Vienna. The United States and the United Kingdom decided to participate and China decided to send an observer. More than 150 countries and several international organizations and civil society are participating. More than 60 countries sign their commitment to cooperate to “stigmatize, ban and eliminate” nuclear weapons. Article II: Any non-NWS party undertakes not to receive nuclear weapons or other nuclear explosive devices from a source; Do not manufacture or acquire such weapons or devices; and not to receive manufacturing assistance.
