There is a good chance of this. Nukes need ongoing yearly maintenance to be operational, without that they are basically just a flying tin can. The whole movie trope of stealing an old nuke and using it doesn't apply to the real world.

Also corruption is somewhat accepted in some countries as it allows those at the top to have legitimate means of disposing of traitors when needed without that hassle of drumming up fake charges.

I read that in the Cold War, the military expected some incredibly high failure rate (30%+) of the bombs due to technical failures. These are incredibly complicated machines.

What ongoing yearly maintenance does a non-hydrogen nuke need?
