Sorry, I was under the impression you were speaking in favor of NATO expansion and think that while the US is bad, it’s emdevours in Ukraine are just (this time).
Also “critical support” for what, Russian imperialism? Why does Russian imperialism deserve “critical support” while western imperialism deserves direct opposition?
Revolutionary defeatism
Recognizing that yes, Putin’s Russia is a bourgeois state with highly questionable rights for sexual minorities and a husk of its former Soviet glory, its re-nationalized industries are a target for the US imperialist emdevours ripe to be privatized again. (You can see how the NATO supports racist nawalny,.but not the largest opposition force in Russia instead, etc.)
To understand the geopolitical context of the NATO proxy war in Ukraine against Russia it helps to watch the Mearsheimer lecture on it (hardly Russian propaganda)
