I’d bet my left tricycle that more than half of Russia’s nuclear stockpile is behind in its maintenance and unusable.
Knowing the USSR’s penchant for deception, if Pootie-Poot goes so far as to advertise to the world that his army is neglected and underskilled (= Ukraine), what are the odds he’s still paying full fare for maintenance of his nuclear weapons, which no one not in the program could know the truth of? He’s just the sort of lying so-and-so who would dare the world to call his bluff.
You can be sure that Putin’s military have disassembled most of their nukes so they could try to make vodka out of the plutonium.
