BRICS is a feel good, fashion show photo-op.
India is heavily reliant on the West for continued investment, both civillian and increasingly - military tech, access to higher education, basic level innovation and long term progress.
With a stroke of a pen the American President can kick out all Indian international students, curb and choke them by blacklisting any company that does business with them and ban any future immigration from India for example.
Only China can survive financial and technological backlash from the West. Russia barely somewhat survived due to China's help.
If BRICS is trying or going to "destroy" the U.S. dollar, it means the U.S.A wants the dollar destroyed.
The Americans are just way too smart.
