If you include the global south [...], most of the world sides with Russia.
I don't know if the global south really sides with anyone so much as watching from the sidelines. Not honoring sanctions isn't the same as actively fighting.
It's a proxy war the Western Imperialists via NATO but under the hegemonic control of the US in particular, is waging against the rising challengers of that hegemony.
i.e. Eastern Imperialists - let's call them by what they are. This isn't some noble quest to liberate countries from US control. It's a maneuver to secure more power in the space before the red line of nuclear deterrence.
This isn't freedom vs. imperialism, it's just imperialism. The People's Republic China has always been its own hegemony. Russia lost much of its sphere of influence during the collapse of the USSR, but it has made a solid effort to reclaim it since, e.g. with Belarus, Chechenya, Georgia and now Ukraine.
Neither the US "interventions" in the Middle East nor Israel's "Operation Swords of Iron" against Palestine nor Russian "special operations" nor (PR)China's claim to Taiwan (ROC) nor all the other power grabs I won't bother listing (or don't even know about) are anything but imperialist ambitions. There are no saints among the leaders in this global standoff.
But ultimately, it's the people that pay the price in all of these conflicts. Human suffering, oppression, exploitation transcends all borders. We may have different leaders, different cultures, different experiences of life, but we're united in the fact that we both will be the victims of this.
