Did I not comment in an earlier post that Putin and his advisors were not dumb! They should have had anticipated all that the west could do including economic sanctions, etc... - "Russia-Ukraine War 101". I wrote Putin had no intention to occupy Ukraine, but more to change the world order - the US-centric world order around the petrodollar.
In the short term, Germany(maybe some others as well?) cannot go without Russian gas through the Ukraine pipeline. To pay in Rubles, the German banks have to open Russian bank accounts with some Russian correspondent banks; only then could they buy/sell Rubles.
I think Putin's action here would not change the status of the USD as petrodollar much in the short term. The US must be challenged much further, militarily and economically, before the petrodollar could be replaced.
