As stated many times before, the value of the ruble against the dollar is not a meaningful reflection of the state of the overall Russian economy. You need to look at Russian GDP, inflation, interest rates, oil/gas revenue, imports/exports and other internal Russian indicators to obtain a proper picture of the state of the Russian economy.
You are an imbecile, imbecile. Russia must plan on staying in Ukraine forever because other than nuclear weapons they cant destroy Ukraine,as the the 3 years has clearly shown.
