Either all nuclear weapons should be eliminated (unrealistic), or more countries should have them. The current system is a handful of countries imposing and maintaining an unfair advantage over everybody else.
the issue with proliferation is that it increases the risks of nuclear materials and knowledge falling into the hands of really dodgy non-state actors in the event of state collapse/incompetence. Like, even total rogue states like DPRK and Iran are "rational" enough of their weaponry that they would understand the risks of using them unilaterally; logic that may not apply to terrorist groups that could spring up during a civil war.
