No each map is explained on that comm. You assigning it 'imperial core' and asking for an explanation is some JAQing off sealioning imo. Theses maps correlate how interests of countries align around various issues, and the 'same map' comes up a lot because of how these same countries often agree on things in contrast to the the rest of the world. It's not some socio-political theory, it's just the reality of how these countries align into blocs that correlate with maintaining the current US hegemonic status quo.
The two maps that really 'explained' this concept for me were the map of countries that 'condemn China's treatment of Uyghur Muslims' contrasted with the map of 'countries that recognize Palestine'. It shows how this bloc of countries want to demonize China while supporting the ongoing genocide of Palestine's indigenous peoples. The principles they espouse are unmasked in the light of the truth of this comparison.
Saying I am sealioning is an accusation and not an opinion besides also being wrong. Here is one in return: Acting like the map is not usually considered to portray the imperial core is intellectual dishonesty on your part.
First you accuse me of sealioning and then you hide behind an "imo" like that is just your opinion. There is no such relativistic position on an objective matter. You are wrong to claim so and cowardly for disguising it as an opinion. With this in mind it does not surprise me that you stoop even lower with trying to berate me for my style of writing. Who tf acts like that?
