You wouldn’t even need a working one. A lot of nuclear responses work by going off the moment a likely missile fitting that criteria launches, since it would be too late otherwise.
Someone making the wrong decision at a given time could easily cause everything to go up in a nuclear conflagration. It’s nearly happened before.
While this may well be true, Russia has so many nukes and nukes are themselves so destructive that it’s kinda cold comfort even if 90% of them fail
