A more accurate title and thesis would be "How the West's historical amnesia took everyone for a ride".
The West has made a very concerted effort to ignore the historical and geopolitical context (and misrepresent it where it must mention it) surrounding the situation. The conflict did not begin in 2022 by Russia. The only way the West has managed to gain and hold support has been by deceptively misrepresenting the reality of the situation in order to rally everyone around a perceived Evil. They don't bother describing what the people in the actual territories that asked for Russian support want. They don't bother describing how Ukraine has bombed its own people. They don't bother to describe how, partially due to Ukraine's abuses, several regions voted to join Russia. They don't bother to describe how Russia was invited by those fighting for their homes and families against Ukraine. They don't comment on how millions of Ukrainians have chosen to immigrate to Russia since Ukraine bombed its citizens in 2014. They don't dig in to why the majority of the global population supports Russia here.
This is not Russian imperialism or colonialism. This is not Russian aggression. The attempt to describe it that way is dishonest and, unfortunately, most people don't care enough to actually inform themselves so this portrayal catches on rather easily.
The Western media has taken advantage of the fact that very few people are informed about historical context, and that most people don't care about context. The Western media has taken advantage of the fact that people like to be united against a Big Evil, in a fully black-and-white way, devoid of any context and nuance.
You didn't answer what I asked.
You said that capitalism by definition leads to imperialism. I asked how socialism by definition precludes imperialism.
