Approved on July 7 by a vote of 122 to 1 (Netherlands, the only NATO state to participate), with one abstention (Singapore), the nuclear ban treaty will open for signature on September 20 at the United Nations and will enter into force when 50 states have signed and ratified it.

The treaty prohibits the development, manufacture, possession, and use and threatened use of nuclear arms. There are several pathways for nuclear-armed states to join the treaty provided that they verifiably eliminate their arsenals (the US, UK, and France together declared that they will never join). There are also obligations of assistance to victims of nuclear use and testing and of environmental remediation of contaminated areas. 

 

Origins and Significance

At a minimum, the nuclear ban treaty is a powerful and eloquent statement of the political, moral, and legal standards enjoining non-use and elimination of nuclear arms. It is grounded in an understanding of the humanitarian consequences of nuclear explosions, and innovatively  acknowledges the suffering of the victims of the use of nuclear weapons (Hibakusha) and of their testing, as well as the disproportionate impact of nuclear weapons activities on indigenous peoples. 

 

At a maximum, the treaty will serve as a framework for the achievement of a world free of nuclear weapons. In this aspiration, it reflects the aim of the 1997 Model Nuclear Weapons Convention whose drafting LCNP coordinated. If the treaty is not itself used as such a framework, at least it points the way toward a convention - a comprehensive agreement on the permanent global elimination of nuclear arms.

 

The ban treaty effort grew out of conferences on the humanitarian consequences of nuclear explosions held in 2013 and 2014 in Oslo; Nayarit, Mexico; and Vienna. It has deeper roots in the formation of regional nuclear weapon free zones, starting with the 1967 Treaty of Tlatelolco establishing such a zone in Latin America and the Caribbean; in General Assembly resolutions, notably resolution 1653 of 1961, in which a sharply divided Assembly declared the use of nuclear weapons to violate the UN Charter and other international law; the General Assembly's request to the International Court of Justice for an advisory opinion on the legality of threat or use of nuclear weapons; and in persistent efforts by non-nuclear weapon states in Nuclear Non-Proliferation Treaty review meetings to extract a commitment from the nuclear weapon states to commence a concrete process of negotiating disarmament. With the nuclear ban treaty, countries largely of the nuclear-weapon-free Global South, joined by Austria and Ireland, have escalated the struggle, declaring that nuclear weapons must be legally prohibited and eliminated as has been done with biological weapons, chemical weapons, landmines, and cluster munitions. 

 

As the Japanese affiliate of IALANA has observed, a principal task now is to convince countries dependent on nuclear arms of the values and logic underlying the nuclear ban treaty. For reflections on the contradiction between the attachment of the world's major powers and their closest allies to nuclear arms and the ban treaty, see this excellent piece by Richard Falk, a member of the LCNP Board of Directors, " Challenging Nuclearism: The Nuclear Ban Treaty Assessed."
