Will a ban on nuclear weapons be useful if states like North Korea won’t sign it?


A ban on nuclear weapons will establish an international norm against the possession of nuclear weapons, which will help to reduce the perceived value of such weapons. It will draw the line between those states that believe nuclear weapons are unacceptable and illegitimate, and those states that believe nuclear weapons are legitimate and able to provide security.

If nuclear weapons continue to be portrayed as a legitimate and a useful mean to provide security, non-nuclear weapon states might aim to develop such weapons themselves.

A ban on nuclear weapons would create a global norm against nuclear weapons, which would not only put pressure on both nuclear-armed and non-nuclear weapon states to reject nuclear weapons permanently, but it would also set the stage for future progress in states like North Korea should its domestic political situation change.
