Threat of use: The threat to use nuclear weapons is central to the nuclear policies and practices of the nuclear armed States and their allies. As such, UNFOLD ZERO supports the proposal to include a ban on the threat of use of nuclear weapons in the ban treaty. Some States in the negotiations oppose the proposal to prohibit threat of use, arguing that it is hard to define such threat. However, a prohibition on the threat to use force in international relations is part of the UN Charter. The International Court of Justice used this, in conjunction with other customary law, to affirm in 1996 that the threat and use of nuclear weapons is generally illegal.                                                                                    Financing: A considerable number of States support the proposal for the ban treaty to prohibit financing of nuclear weapons. However, some other States in the negotiations argue that such a prohibition is too difficult to implement.                                                       It is likely a specific prohibition on financing will not be agreed, but alternative language would be adopted that prohibits States parties from assisting, encouraging or inducing anyone to undertake activities prohibited in the ban treaty. This could be interpreted as including investments in nuclear weapons corporations.
