I believe that economic and cyber war are the weapons of the future. You don’t need a million man army, when you can paralyze your enemy without taking a shot. i agree that Russia and China are uneasy allies, but look at what Roosevelt and Churchill accomplished while working with Stalin. The problem is they never took care of him once WWII wound down.
Suspect that after they beat us, Russia gets east of the Mississippi, and China west of the Mississippi. China gets Japan and South Korea, Russia gets western Europe. How they split Africa and South America I don’t have a clue. Same for Canada.
Then we will see the dawn of the New World Order. One worldwide currency, and control shared by the two allies.
