I don't think you have any grasp of the political situation if you think your strawman represents a position anyone of reasonable political understanding holds.

The fact that you think the predominant position of "tankies" is that communism just needs to be done "right" is also evidence that your self-assessment of being "fairly socialist" is completely detached from reality. You're still fighting through Western propaganda.

The reality of the situation is war is going to happen, whether the US starts it or someone else starts it. Who starts it doesn't actually matter, what matters is the entire structure of politics around the war. I don't like war, it's terrible, but certain conditions make it necessary, and the US is far and away the architect of these conditions. The Russian invasion of Ukraine is no exception. This was a structure put in place by the US. That Russia crossed the imaginary border and made the declaration of escalation in Feb 2022 does not mean Russia holds special moral standing in this conflict. Russia assessed the same system flows that the US assessed and decided now was the time to escalate the conflict, but the conflict has been hot since 2014 and the US has been there stoking that fire since well before the bullets started flying.

If you think crossing the border and declaring the escalation holds moral standing but the entire 30 year program of the US to create these conditions does not, you might just be a standard run of the mill liberal without a hint of being "fairly socialist".
