Nuclear disarmament should arrange towards the complete and total elimination of nuclear weapons, participation of nuclear-weapon States in implementing their disarmament obligations. For example, the piecemeal reduction of nuclear weapons and commitment to conditional security assurances would be regarded as a mockery of non-nuclear-weapon States and it would only deepen mutual distrust. Complete and total nuclear disarmament, namely, the commitment of nuclear-weapon States to negative security assurances, withdrawal of nuclear weapons deployed outside their territories and total elimination of nuclear weapon arsenals would satisfy the expectations of the international community for fulfilment of disarmament obligations.
