Sorry for the truth but the rouble is worth more now than before the sanctions. But yes it will cost Russia something but they have very little out of country debt, they have the natural resources and lots of grains to eat.. Think about this. When you own natural resources you have a product that you can do something with, then the central banks of the world print money out of thin air that have nothing backing the value of those dollars and want to trade you for some of your natural resources, so you get a dollar backed by a bankrupt government. That is not a good trade for natural resources. The EU will find out this winter just what keeps the house warm and fist full of Euros or Russian natural gas
