The thing to remember is that nuclear weapons are not like other bombs. They are incredibly complex and need constant maintenance or they will be useless after a relatively short time.

They can't be "stored" anywhere where there aren't the most skilled technicians to maintain them constantly. They will tend to become big radioactive paperweights otherwise.

Oh please, we package and send nukes all over the place in ships and planes and trucks that expect to get shot at during a war. They ain't made of frilly little lacy thangs. The won't break if you drop them them on your foot. And unless they have some specific requirement like replacing tritium (and even that has significant shelf life) they are as shelf-stable as some MREs.
