I am pretty sure that European states are already storing data that is out of reach for the US government, and I don't understand how Congress could legislate against this, short of an act of war.
There are certainly exceptions, but a lot of European Governments use Azure or Google for their office applications, including different law enforcement agencies and militaries.
Indeed. My point, however, is that Congress cannot pass legislation to compel European governments to share data with the US if/when they decide not to. OP is making a weird claim about the practical impossibility of escaping US data collection.
