Once ratified by at least 50 countries, the treaty will ban them from acquiring the weapons or allowing them on their territory. The nine countries that already have nuclear weapons boycotted the proceedings. But observers think that the treaty will further the goals of nuclear disarmament by stigmatizing possession of the weapons, as have past global bans on anti-personnel landmines, cluster bombs and chemical and biological weapons. In March, more than 3,000 scientists, including around 30 Nobel laureates, penned a letter in support of the ban.
