In fact, it is absurd to claim that is the issue. Does every country have the "right" to have the means to totally destroy the USA in a nuclear attack or to irradiate the entire world in such an attack against another country? Do you think that such "rights" exist or ever have among and between nations?
Such a level of being naïve and so zippy pinhead lost in platitudes it is difficult to believe any adult could even think in those terms.
Does Vatican City - a country - have a "right" to 5,000 intercontinental ballistic missiles with MIRV warheads? What about Tulavu with 12,000 people? Apparently some people think so.
What about a state or a city? Do the citizens of Mosul have a "right" to nuclear weapon?
Discussing this in terms of rights is absurd.
