It’s a non-starter, the Germans will never allow sanctions.
Germany won’t cooperate, and we could make a list a mile long of others who won’t or who will lie about participating.
Even energy supplies to Europe is so far in the future that it’s not even worth discussing. Russia already has pipelines to China. They just reverse direction on that fuel, and China’s getting their energy from pipelines and not from tankers.
If the west wants to confront Putin, then they’re just going to have to confront him. And they don’t want to do even that. ABMs in former Warsaw Pact countries? Nope. A new version of the Fulda Gap based out of Poland, Czech, Bulgaria, Hungary, Estonia, and Ukraine? That isn’t going to happen.
That is confrontation. That isn’t sending a message. That is sending a double-dog dare ya.
