There are three sets of reasons for a palpable rise in nuclear anxieties around the world: growing nuclear arsenals and expanding roles for nuclear weapons, a crumbling arms-control architecture, and irresponsible statements from the leaders of some nuclear-armed states.
On 7 July, 122 states voted to adopt a new Treaty on the Prohibition of Nuclear Weapons. It articulates the world’s collective revulsion at the humanitarian consequences of the use of nuclear weapons, under any circumstances. The foreseeable effects of use in the indeterminate future make the possession of bombs today morally unacceptable to the international community. The treaty’s primary intent is to stigmatise nuclear weapons through a legally binding prohibition instrument in order to induce movement towards nuclear disarmament by the bomb-possessing countries.
