i would think hidden nuclear bombs needs some maintenance on a regular schedule
By people technical enough to keep them operational. I thought that the radiation put out by these warheads tear down the electrical support systems.
So in a nut shell, I don't believe it would work,
or should I say I pray they don't work,
maybe someone with Nuke background could elaborate......

It depends: the suitcase bombs that use tritium would fail if the tritium is not renewed. But that is not what was described. Nukes can have a very long shelf-life - several years - depending on how they are made.
