Even in this ludicrous fantasy where 95% of Russia's nukes don't work, it's still not meaningful unless you also assume there is no way for them to check which 5% of their arsenal is working, and presumably those warheads are deployed for the most lethal systems they have.
You also have to concede that Russia has reduced their nuclear stockpile by like 50% in the last decade. do you assume they decommissioned their best nukes or their worst nukes?
