That’s wrong though. It’s not like the nukes are located in Moscow. There are tons of launch silos all over the country. And most of those operate on a sort of dead man’s switch, as they launch at some pre-selected targets (and the US, for example, is definitely on the list) unless the timer is reset daily. There are also autonomous crews that have an order to launch if they lose contact with command for a long enough time.

Can you trust anti-air defences to intercept every launch? While possible, it’s unlikely, and missing just one leads to awful consequences.

Plus, depending on how true this is, there might be radioactive-tsunami-type torpedoes on Russia’s subs.

That’s why everyone is so careful not to attack Russia directly and why Russia can do all the shit it does, and just get sanctioned instead of getting an open war escalation.
