Putin must have expected the/this response from the West, every bit of it. Sure, MSM will assure us that he did not, but that's ridiculous, he knew and did what he's done nonetheless. His enemies never embraced him even during the calm period after the USSR fall. There was always side remarks, cut downs, rubbing his nose in it, et al. That wasn't lost on him, make no mistake. He toted up the insults, forgetting not a one.
He's obviously made his deal, his arrangement with China. That is the linchpin and our chief concern. It must be a deep and assured partnership for the long term, otherwise Putin woulda never crossed over into Ukr with this deadly of a commitment. [Most likely] the quid pro quo is China gets to whack out Taiwan with Russia's assistance, blessing. Will/Would we intervene at that point? I can't seriously imagine we would, but I may be tragically surprised. We're not going to go nuclear over a hole like Taiwan, that's what China/Russia are wagering. Hope the wager is a winner.
