I don't see it like that.
The west's HUGE fuck up was weeks and months ago with wishy-washy talk about sanctions and not spelling out really, really, really clearly to Putin what the consequences for invasion would be and just how bad it would be for him personally. Then when he made his initial proclamation of the annexation of parts of Ukraine, we imposed really limp sanctions. This gave him a big green light to carry on.
Since then, we have to a much greater extent "thrown the book at him". Although we can still do more. But I am sure the west's response is FAR more coordinated and severe than he was bargaining on. The problem is, having gone into Ukraine - which we really should have prevented in the first place - he now has nowhere to go. He cannot back down. That's why we've really fucked up. I seriously wonder if he regrets where he is right now - I suspect he does.
And I don't see him attempting the same with e.g. Finland or Sweden. The situation is entirely different. He tried to justify the action against Ukraine on the basis that it's natural, cultural home is Russia. And even so, he's seen such and enormous domestic backlash. He cannot possibly make the same claims over Finland or Sweden etc. He'd be completely mad to even try it, and contrary to the lazy narrative, he is not mad.
