I have a lot of personal theories how my country can best cope with future geopolitical adjustments. If I were in charge, the first thing I would do would be to close most foreign military bases. We can have the strongest military in the world and have them largely based in the US. I think the US Navy continues to be a good investment, but I would cut back a small amount on intel and other military branches.
During petrodollar era, the 1970s and 80s, the dollar was used less than it is today. (Certainly within the USSR and even the Russian SSR.)
We de facto banned Russia from using the dollar in 2022 [1]. That it took Moscow over two years just get down to 50% speaks volumes to the dollar’s strength.
