So you have any problems with any other nations colonialism or just Russia’s? What country you from?
Spain. Or born Spanish anyway. I have one of those EU brown passports. Yeah, at colonialism we were world champs at one time.
Any other such fundamentally hostile colony would have split off in the age of anti-colonialism. Most of Russias hostile ones did, in 1991. Chechnya was for some reason not permitted to do so.
