I think ideally there would be no nukes in the world, because they are dangerous. But nukes do exist. If western countries got rid of their nukes, then the remaining nuclear countries would be able to do what they like. “Surrender to our demands or we will nuke your cities.”
Potentially. I think it depends on how they’re used. If a country decides to completely disarm itself though, then it’s entirely possible that other countries will seek to invade and subjugate.
