Rationing of energy would happen if Russia completely cuts off gas supplies to Europe. Prices would essentially become meaningless, says this report. Supplies coming through Ukraine are limited to 18% with the rest of the 38% Russia supplies to European Union coming through other countries or new pipelines. LNG supplies from the US are increasing but not enough infrastructure has been built for this.

This may explain also why Russia is acting now on NATO enlargement that it sees as its concern. Increasing shift to LNG and other supplies would make EU less dependent on Russia. NATO countries are also not spending enough on defense with Germany not yet at 2% and Scholz only going up to 1.5%. Russia has modernized its defense capabilities by comparison, the US mired too much in localized wars in Afghanistan and Iraq. 

Russia was never "a regional power" as Mr. Obama had said with a vague understanding of European history, even while America's resources were wasted in two wars in Afghanistan and Iraq where American interests were not involved. Today the realization is that European Union and American leadership had failed under leadership of Merkel, Macron and in the Bush and Obama years.
