In total fairness, they could have abuses of power up to and including SA of many kinds, and it doesn't necessarily make them bad at maintenance.

The shit tier job they did on the rest of their materiel, and that leading to the deaths of a bunch of their soldiers, on the other hand, is pretty strong evidence. Are the nukes maintained by maximal Russian patriots?

The myth of the super capable Russian army also protected Russian interests, and look how that's going.
