You aren’t brainwashed, you are just enculturated to a very reactionary ideology. I actually agree that it’s better to analyze them as separate countries for the purpose of something like this graph, but this thinktank (which, to be clear, is very Atlanticist, i.e. aligned with your geopolitical views) is almost surely gunning for having their little infographics be diplomatically palettable in hopes that they get used by important bodies.
