No, it is not being poked. It is being contained (just about).No, it wasn't being poked, but it currently is (and again, rightly so), and Putin is feeling it, too. The question is, how hard do you poke, knowing the potential outcome for all?
As I said earlier, it's a long game and yes, horrendous for Ukraine, but poking to far/hard too soon will do nobody any favours.
