Yes, the developing BRICS situation is interesting.
The bloc is expanding. They want to create a rival international currency to the global dominance of the US dollar on markets (mainly for political interests, of course, particular as China and Russia see themselves very much in competition with the old powers of the US, UK and Western Europe). India has just put a rover on the moon (despite still receiving millions of pounds in aid from the UK!)
The US is already concerned about the economic power of China; the NATO and AUKUS powers are resisting both Russia and China's military ambitions; India and China have the largest populations in the world, and India's young especially are on the move; China and Russia are extending their influence in Asia, Africa and South America.
I don't think BRICS will achieve lasting greatness as a power bloc as those nations themselves are not internally as robust or as united as the UK and USA were when they rose to power in their respective times, but it will be interesting to see how far they can go. TBH, their union doesn't even really need to be that successful, just enough to concern the 'old world' powers so much that it influences their behaviour too. And those current and former world powers themselves are not as stable as they once were either, with and the USA, UK and EU suffering a lot of internal political upheaval and crises of identity over issues like migration, and even things like gender politics.
Lots of potential for future clashes - diplomatically and economically at least - between the two groups of nations.
As to which is King of the North, biblically speaking, and which King of the South, that's difficult to say.
It could be as easy as and the Global North=KoN and Global South=KoS, but remember two things: 1) those 'kings' originally got their designation from where they were in relation to the nation of Israel (north of the country or south of it), but came to represent two styles of government - KoN more militaristic and ruthless, KoS more superficially diplomatic and democratic. So by that, it would seem most of nations in (or invited to join) BRICS are more like the KoN in style.
Also, wouldn't it be a delicious irony and not surprising of the lying and deceitful nature of Satan's world, for the designations to be reversed? (Global North=KoS and Global South=KoN)
So I think the jury's out on which is which until we see more of how relations between the two blocs develop.
