But remember, Russia is part of Europe and has itself been a colonial and imperialist power.
Imperialist nations fight each other too which resulted in WW1 and WW2.
Today they still form alliances and fight among themselves for resource, control, and dominance of the world while other countries become their battlefield.
Any nation not showing obedience, allegiance, or support would be sanctioned, isolated, sabotaged, attacked, or occupied by these imperialist countries.
