I saw a video depicting and actually showing Russian gold reserves.
Russia has literally tons of gold that can be used in foreign exchange as necessary in a real bind. Putin has been diligently working to enlarge the gold reserves anticipating just such a situation as the one now upon him
If the ruble is not freely convertible for gold, then those reserves dont mean much. And if they are, there goes the gold reserves. Why Nixon closed the dollar gold window in the 70’s because countries were actually using it.
