The war itself began as a war over very real security concerns but may become something else.

I see it as puppets of imperialists fighting against aspiring imperialists. Russia is not strictly imperialist, at least comparatively to the western empire. But it is hard to deny that there are those actively pursuing it. Regardless of this I see them as an essential security partner to China and an essential front against the west that get critical support because their collapse would be very bad for socialist goals.
