Ukraine Crisis This also reads like fiction.
I really think people here have a tendency to extrapolate all sorts of stories from a minimum of facts.
We have seen an irrational Putin. Which is a variation on the theme whenever leftists proclaim "but why do poor people vote against their interests? whine whine". It's elitist and almost always misplaced. Putin is not an idiot, he's not irrational. He simply thinks other things are important than most "Westerners" fed on a steady diet of neoliberal economic policy, white saviour complex while being blind to the financial and cultural oppression of other countries and sometimes outright wars (based on lies). He doesn't care about the legal order so the whole "it's an illegal war" is not a consideration at all. We know this because Russians bomb the shit out of civilians in every war and those rules are older than the UN charter.
Then there's the "Putin is a mastermind" kind of exposition you just wrote. We see coping and market mechanism developing alternative financial systems, we see increased trade between Russia and countries that didn't join sanctions. These are reactions to circumstances and I don't believe for a second these steps and consequences can be predicted by any type of accuracy because you cannot accurately predict the shape and form of sanctions, the level or type of support by the West and even your own allies. etc.
Then there's the "imperial" Putin because he referenced tsaristic Russia a couple of times (and boy, what a lot of books that invited). I'm sure lizards dream of being dragons too. That doesn't automatically mean they actually try to breathe fire.
I still believe the simplest explanation is NATO expansion or the threat thereof. The BBC in 2008 on Georgia:
President Saakashvili has made membership of Nato one of his main goals - and Nato agreed in April 2008 that Georgia would become a member of the alliance at some unspecified date in the future. — BBC
I think the similarities in 2008, 2014 and now in 2022 are obvious. It's the simplest explanation for Putin's actions. A basic realpolitik interpretation of the geopolitical situation where Russia considers NATO an
existential threat. The knee-jerk reply that "NATO is a defensive alliance" is neither here nor there - it's not about what we believe, it's what Putin believes that drives his decisions.
