I'd consider the serious escalation of offensive (cowardly) acts were carried out by Russia many many years ago repeatedly, increasingly, throughout Europe (elsewhere too), with mild consequences. Got seriously unabashed escalating further. Being cautious with the nazi Germany blew into the face of the World, will definitely not work with the imperialist Russia either. China acts on behalf of Russia here - Russia being coward for open confrontation with anyone (believed by them) able hitting back hard. China has secondary benefits for self as well.

Damaging infrastructure is already a severe escalation. Should not have done that.

I've always wondered how subs handle tidal flows there, and how challenging the tidal flows are.

How severe an escalation would it be?

As severe as... say starting the largest war in Europe since WW2 right at our doorstep? Or as damaging our critical infrastructure? Or manipulating our democratic processes?

It's time the West pulls its head out of its ass. We're already at war, whether we want it or not.
