As for the BRICs currency scheme, it suffers from the problem that the primary members cannot and do not trust each other. Even now, for example, Russia has a large balance in rupees on deposit in India but no practical way to spend it or convert it efficiently into a transactional currency like the dollar.

NATO caused this situation and 100 percent responsible. Your one-sided view of history sounds exactly like the Biden Admin MSM talking heads who stole an election and have spied on all Americans so that they can keep control of the country.

Even a horse isn’t as blinded as you DNC trolls.
