I will be very surprised if Saudi Arabia doesn’t follow Iran and Argentina into BRICS. The Saudis fear and despise the two major western foreign policy initiatives, the exportation of the New Green Deal and western perversions. The western assault on Russian banking and their economy also pushes the Saudis and the rest of the non aligned world towards alternatives. The globalists in Brussels and DC could bring the same sanctions to bear on Riyadh or New Delhi. They are wisely taking proactive action now.
With the western world hell bent on cultural/political/economic suicide, Saudi and a few other major players would be likely to see the future belonging to BRIC.
