Ah yes, the American billionaire who's in service of the empire is secretly an anti-imperialist and pro-BRICS.
He'll take on the Deep State any minute now. With help from Xi and Kim, he'll put an end to the Marxist globalists that control the world! 5D Chess!! 
It would be very funny if the US joined BRICS.
Saudi Arabia already did. The US is already inside BRICS lol.
Real talk is it would be funny, but also incredibly hopeful (that is, if the US didn't enter to sabotage it all- which for the foreseeable long-term it definitely would). All they and the west at large need to do is accept being just another country, working together and trading with other countries as equals, minding their own business and focusing on developing themselves... of course, it could never happen within the current system.
