I'm guessing that their nukes are in as good condition as their military. Probably dirty bombs at best.
Imagine you are in charge of maintaining the one weapon that is least likely to be used. Are you going to spend all that money actually maintaining it, or are you going to buy a shiny new yacht? What are the chances that you will ever get caught?
Nukes take a lot of upkeep.
As stated before, the most dangerous person to a firearm owner is themselves. roughly 2/3 of firearm deaths in the USA are suicide.
