Kicking Russian corruption and influence out of Europe is certainly a “vital American interest”. If you don’t believe me just ask those Americans in Texas with good new jobs exporting energy to Europe.
Germany is paying 4x the price of gas now having to buy from alternative sources making their industries uncompetitive globally. How long do you think the Germans will put up with that? I saw an interview with an ex CIA agent who contends most of the major European leaders have been bought out or blackmailed by us to do our bidding. They have a deep state working against their own citizens just like we do. Eventually their public will wake up to this fact. Germany is the economic engine of Europe and now their industries are being forced to move elsewhere to remain competitive.
