Disarmament is much necessary:

• Given the potential devastation from the use of even one nuclear weapon, global nuclear disarmament must remain at the top of the United Nations agenda. 
• It would be the height of folly to take for granted that such weapons were too terrible ever to be used and that States would keep them for deterrent purposes alone. As long as some States had developed such weapons and as long as States stocked such weapons, there was always a risk that they might resort to using them. 
• Some might view progress in the field of weapons of mass destruction as the least promising. Indeed, during the past year the world had witnessed several regrettable events, including a stall in the Treaty on the Reduction and Limitation of Strategic Offensive Arms (START) process and the advent of nuclear tests in South Asia. 
• The lack of respect by certain countries over security assurances to non-nuclear-weapon States was another area of concern. The difficulties in establishing a total ban on nuclear tests and on the prohibition of the production of fissile material for weapons purposes could also justify a certain gloom. 
• Countries possessing such weapons have well-funded, long-term plans to modernize their nuclear arsenals. More than half of the world’s population still lives in countries that either have such weapons or are members of nuclear alliances.
