By many measures Europe is in fact pretending to be sovereign. I think it is what they are attempting to do at the moment, "stop pretending to be sovereign" and actually BE sovereign. At least that seems to be the claimed attempt.
If anyone is not sure why I would say that Europe is not sovereign, I will answer that question if you ask, but considering the current state of things and even just this discussion about data sovereignty and other related topics about using and deploying European technologies; I suspect most, if not all have a sense that Europe is in fact not sovereign... and that's without even pointing out huge elephants in the room like the 275 US military installations across Europe, and not even to touch on the fact that NATO is really just ** pulls curtain back ** SURPRISE! ... America, Europe Division.
If the gloves were off then the equation would be different. A fight with the rest of NATO would be conventional warfare where the US has a giant advantage.
what are you even talking about? nowhere is anybody on any side even hinting that the problem with NATO is it stops the EU from having a war with the US.
the problem with NATO is that it shares a burden and some feel they don't want to pay their obligations and some feel their share is too much, and then it was based around invasion of the territories of western and then middle europe, and ukraine came along and it's a serious threat to middle europe but its not covered by NATO.
