Why can't the globe be nuke-free

The 189 countries that attended the 2010 Review Conference of the Parties to the Treaty on the Non-proliferation of Nuclear Weapons (NPT), which ended on May 28, agreed on a "final document" at the last minute. The document, aimed at moving the world closer to nuclear disarmament, covers the three pillars of the international nonproliferation regime - nuclear disarmament, non-proliferation and cooperation in peaceful use of nuclear energy - and puts forward systematic action plans in every respect.

Nuclear weapon states, according to the "final document", have promised to take effective measures toward nuclear disarmament, reduce the role of nuclear weapons in their national security policies and report disarmament progress to the Preparatory Committee for the 2014 NPT Conference.

The document asks all Middle East countries to attend a conference in 2012 to create a nuclear-free zone, and urges Israel to abandon nuclear weapons as quickly as possible and join the NPT.
