The question was about equivalent / proportional response, for which RU has more leverage and impose more costs by virtue of being more resource/economically autarkic. NATO of course free to escalate if they think they can win the escalation game (i.e. sinking RU fleet), then it's a question of how far RU willing to go to fight NATO, in which case it's matter of who has more to lose and can stomach more loss, up to and including tactical nukes. Does RU want full spectrum fight with NATO that could go nuclear? Probably not, but does RU think it can sabatoge NATO maritime infra with managable conesquences, IMO yes. NATO propaganda will also have to work hard trying to rationalize going into recession for a buffer state versus going war with a nuclear state.
