The argument is that the EU cannot and should not even attempt to prevent unaccountable spying on its citizens by foreign states, or it will have its legs broken?
I'm assuming "having its legs" broken refers to having german car companies treated by the US like silicon valley tech companies are treated by the EU?
Are the German car companies spying in the United States?
(OK, that's snarky, but the car companies did actually have to pay out .. because they defrauded US consumers! Not all "crime" committed by companies is made up to sell trade restrictions!)
So... like they already do? EU car and airplane manufacturers already produce their US models in the US due to tariffs rendering importing EU models uncompetitive.
