"The Global North", "The West", "The Global South" ... all nonsense. Way too broad strokes in nearly every single discussion. I have never seen a single argument using one of these that actually matched the whole group (even excluding those where membership is a topic of debate in the first place). We should abandon them all.
Weirdly, it's still orientalism if you use a different compass direction.
We all know the real test is whether Hollywood would give you the Mexico filter or not.
So to see South Africa come celebrate Russia's conduct cast doubts on their intentions. Do they too just want a ''multi polar world'' because they aim to slaughter their neighbors for the glory of empire?
Geopolitical distance cuts both ways.
Europeans, even Western Europeans, generally have some familiarity with the Russian state and what it's actually like, if nothing else because of the visibility of sizable populations of people who have moved away from Russia but also because of the history of assassinations and sabotage carried out by the FSB in Europe. South Africans are both unlikely to have that context, have significant societal trauma left over from apartheid (which was itself a direct result of European colonialism) and are still experiencing significant material exploitation under the current global economic order. There's a reason why the richest man in the world is a white South African while the average south African earns 50 times less than the average American.
In short, I think South Africa's leaders and their supporters have correctly interpreted that the current geopolitical order is not working for them, have aligned interests with those who seek to create a new one and are sufficiently distant from the reality of the situation to be able to overlook what a shitty excuse for a state Russia actually is or what the natural conclusion of its policies would mean for the people of neighboring countries. The further away something is and the less personal connection you actually have to the people affected, the easier it becomes to just not think about it.
See also that Canadian family who moved to Russia to get away from the gays, were shocked when their assets were immediately frozen on arrival and who are now clearly being forced to make propaganda. On one hand, the fuck did they think was going to happen? On the other, how would they have known?
