127 countries now support creating a treaty to prohibit and ban the possession, use, transfer, or development of nuclear weapons. The Non-Proliferation Treaty (NPT) in which five nuclear weapons states (U.S., UK, France, Russia, China) promised to make “good faith efforts” to eliminate their nuclear weapons while the rest of the world promised not to acquire them, doesn’t ban the weapons.
It is expected that a special UN Working Group for Nuclear Disarmament created by the UN with the help of civil society and friendly governments will move forward on a UN resolution this fall to establish negotiations for a ban treaty! (See: http://icanw.org)
The holdouts for supporting the ban treaty are the nuclear weapons states, as well as those countries that are part of the U.S. nuclear alliance around the world including NATO states, and in the Pacific, Australia, South Korea, and Japan.
