Aside from some factual errors, that's one way to look on things. Another one is that USSR's political top, however incompetent, released their personal fates are tied to their country, while the modern ones plan for a retirement elsewhere (or at least did so before SHTF in 2022).

> USSR: kicked their educated jews out (twice -- pogroms & doctors plot)

Sorry, that's not how it happen (source: my grandfather being a USSR Jew). Pogroms were before USSR (and were a huge factor in USSR becoming a thing) and before most Jews had access to upper education. The pre-WWII USSR was perhaps the most Jewish-friendly country in the world, or at least in Europe (however low of a bar it was at the time). After the purges and the war, with most of pre-revolution intellectual communists dead or worse and fresh-baked ex-peasant comrades now forming most of the bureaucracy, the pendulum came swinging back.

> kicked most of their educated gentiles out in 1917

Forced deportation was a few thousand cases, mostly humanitarians. Most of the educated gentiles left voluntary (showing their good judgement). And then emigration controls were put in place so the rest wouldn't leave - it's just 20's USSR weren't yet the totalitarian state it would latter become and had no machinery to prevent people from leaving.

> used up their remaining human capital as cannon fodder against hitler

Not like Stalin would not prefer to use cannon fodder elsewhere. It just wasn't an option at the time.

> Modern Russia is a gas station and strip mine with decent relations to the south and the east

That's what it was in the aughties. No more.

> Building up their defense sector

Russia already got damn nukes. That's the best defense against symmetric warfare the money can buy - and against asymmetric an inflated defense sector doesn't help much. Russia didn't built up defense sector because of any genuine or perceived threat, rather for the same reason USA does: it's a huge pork barrel.

> they don't get internationally looted again

Looted as in being sent food aid? (Well, truth to be told, this aid came with a heavy load of Mormon and Scientology cool-aid drinkers). The whole "90's looting" is tankies' legend. It was exactly the same kind of de-industrialization that happened in the West - except the social guards weren't in place and the state machine was totally collapsed. Which is certainly not a fault of any other nation.

> the right move for them, and an unfortunate reality for us.

The problem isn't "building up the defense sector". The problem is damn invading neighborhood country. Not only was it an asshole move, it was incredibly dumb because it leaves no good exit option. Even if the hostilities in Ukraine ends one way or another, the "new elite" aka bunch of goons with guns aren't going anywhere.
