Brics is going to survive simply because the Biden State Department has royally destroyed faith in the US led economic system. It is simply an economic union. Any political power is soley regional and not intended as such. The world has moved on from the American forced system, and the alternative to overpriced western societies and the developing world is impressive. African nations are pushing out French and US, and in their place the Chinese and Russians are giving them control of their economies. Several wars like in Mali are coming to a close with the ejection of the west who divided the people within nations with constant war.
The only thing America today offers the world is war.
Peace be with you.
