PTI but such obvious BS needs calling out.
There’ll be a more equal playing field but in the main, the US, Europe and other Western aligned nations will still rule supreme. China is going to go through an almighty demographic crisis, Russia is already going through one that’s set to get worse. That’s not to forget that China already has its designs for Russia and wants its eastern territories, with its abundant natural resources, back. They will strike at a time when it makes the most sense, which will be when Russia has a power vacuum through the natural (or unnatural) demise of Putin.
The only current and prospective BRICS nation that I’d be willing to put money on in the long term is India, but there’s one trump (not him 555) card that the west can play, and should do, that will dwarf BRICS.
