Is Russia’s Intervention in Ukraine Revolutionary?

I wouldn't say revolutionary. There are likely revolutionaries in their ranks that long for a return to the USSR and unaliving Nazis is good, but I wouldn't call it revolutionary in the way we want it to be.

It's revolutionary in the sense that it inflicts a heavy defeat on the imperialists and severely depletes their arsenals. Already the conflict has greatly accelerated the global transition to multipolarity, encouraging Russia but also other countries in the global south that have seen how fickle of a partner the West can be, to reorient, develop alternative trading networks, and reduce their dependence on institutions and financial mechanisms controlled by the imperialist West.
It also destabilizes Europe, one of the two main centers of Western imperialism, politically and economically. This takes pressure off of revolutionary movements in the global south and opens the door to anti-NATO and anti-EU forces in Europe to take advantage of this defeat to agitate for breaking free of these institutions of hegemonic imperialist control which are directly responsible for the severe crisis many European countries now find themselves in.
- There's also another aspect to this which is that the breakdown in trade with the West forced Russia to start developing economic ties with the Global South. Developing countries are now directly benefiting from Russian resources and technology. Russia helping Niger build a nuclear reactor is a great example of this dynamic. So, while the West being weakened forced to pour their remaining resources into a futile war, the rest of the world is enjoying an improved economic situation as a result.
- none of this justifies support for Russia

Revolutionary? I don’t think so. Progressive? Probably so given that the war in Ukraine is a NATO proxy war.

Progressive for the Russian oligarchs which no longer will have to split their pie with Ukrainian oligarchs

- NATO imperialism is the bigger enemy and is the largest external obstacle to socialist construction around the world.

FYI, Joti Brar and CPGB-ML are TERFs.

I realize they're problematic but this is one of the most based and theoretically correct anti imperialist takes on Ukraine I've heard. Also some good analysis of English mainstream politics further in. Credit where credit is due. Hoping they will evolve out of the TERFy stuff.
- Problematic?? They’re just as bad as bourgeois religious institutions attacking people for something like being trans and just trying to survive.

"is a capitalist state trying to subordinate another capitalist state an anti capitalist state effort?" What

It is if you consider the fact that the one capitalist state is breaking away from Western hegemony and imperialism of the dominant capitalist ideology thus engaging in anti-imperialism which is inherently anti-capitalist.
I don't honestly recall that line, is that from when Jyotishman plays devil's advocate?
Anyways I think Joti does a good job of analyzing the geopolitical situation in Europe in terms of Leninism, in particular with reference to Stalin's Foundations of Leninism, and the question of whether or not national liberation is progressive even if not explicitly socialist. The fight against western imperialism is truly the principal contradiction of our time.

  I should've made it more clear. This is not a line from the discussion it's my parody of the title
  Edit: but after watching some of this video I guess I don't really understand the whole of this war and where it really came from. I'll have to learn more I guess
