Is it possible, and perhaps even likely, that most of the world's nuclear weapons don't even work?

But they're constantly discussed, because it keeps the ordinary shmuck in a state of perpetual fear, and will therefore be more malleable to propaganda.
I ask this question because I've come across quite a few documentaries, if one can call videos on YouTube "documentaries", that discuss the very real likelihood, based upon simple accounting and arithmetic, that most of Russia's nukes are duds.
For example, this one.
