Let's say the US balkanizes, becomes decentralized and finally stateless. What to do with the nukes that were left over? Who controls them if there's no central power? Obviously, there should just be no nukes, but let's say other countries that are still states have them, so would it be prudent to denuclearize?
There should absolutely be nukes, and they should be pointed at the rest of the American states until America is properly unified. You know what happens when one state has nukes and the other doesn't.
