Escalation was demonstrated. No it’s not escalation all the way, but this is an escalation in response to an escalation.

Perhaps the size of the response escalation, as compared to a declared or assumed promised response escalation, implies some kind of “bluff” was detected. Like maybe Russia said it’d spend 4 escalation points and instead only spent 2 escalation points, but the relative size doesn’t change the fact escalation just occurred. That’s a bad thing.
