No matter how ill considered it may be, it is the duty of every socialist to support a Socialist polity, no matter how flawed or provisional, attacking a non Socialist one. That's a key part of critical support. It was when Lenin supported the disastrous anarchist revolt, and it was when Rosa supported the Left-KPD revolting 6 months early.
This can sometimes backfire on us if the US supports the socialists, like with the DFNS. But such situations are so rare that I cannot regret supporting the Kurds.
The point is "Yes including the former RSFSR up until it becomes the current RSFSR." also Yes if Cuba invades Haiti, Lula decides Peru has it coming, or Laos inexplicably launches hidden nukes at New Zealand.
