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."

Perhaps not a good one, but still a solution, when a bear gets overly familiar.

what if your nuclear weapon collection is looking too small? How, other than getting more nukes, does on remedy this problem?

You'd think so, but it worked out surprisingly well during the cold war.
