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?

Trying to justify nukes as anything but weapons of mass destruction was the style at the time.
