For the most part, I agree that the US occupation has been benign. Really, they are not protecting Germany from anything, but also not causing many problems. They are perhaps creating some jobs even.
However, when Washington starts blowing up critical national infrastructure to advance its narrow geopolitical interests, that changes.
To be clear, the economic fallout of Germany having to export LNG across the Atlantic instead of through already-existing pipelines is vastly more severe than US closing its military bases (which could be partially reappropriated by a growing Bundeswehr).
Well, that is an unsubstantiated opinion not held by the majority. I did not claim nobody with such opinions exist, one just has to look at the AfD.
Oh and it was Russia that stopped sending gas, long before the pipelines were blown up. You also conveniently don't address my last point, which does not fit the "the US was it" so that's understandable on some level.
> they are not protecting Germany from anything
And the reason for that is that we can hide behind Poland, which is protected by NATO.
