Will nuclear-armed states give up their arsenals if a ban on nuclear weapons is negotiated?

Answer

Banning nuclear weapons is not the same as eliminating them. A ban will be a necessary starting point for disarmament to happen. While the dismantlement of all nuclear arsenals might be a long process, a clear international rejection of these weapons is going to be an essential component of future disarmament efforts.

 

The world did not wait for Syria to eliminate their chemical weapons before the prohibition of chemical weapons was negotiated and brought into force. It did not make the chemical weapons convention any less important, rather it helped the international community to swiftly respond and put an end to the use of chemical weapons in Syria.

 

A ban on nuclear weapons will make the maintenance and development of nuclear weapons less attractive and more difficult, both for existing nuclear weapons possessors and potential new ones. It will create better conditions for effective disarmament measures.
