You seem to be completely out of touch with the way the USA has been behaving towards the EU as of late, maybe get with the times and then report back.
Last I checked China hasn't threatened to take over either Canada or Greenland, has not started any major wars for which they expect the EU to pay for cleaning up their mess, has reasonably sane leadership and on top of that has been a fairly trustworthy business partner that does not engage in whim driven economic warfare. They also have a bunch of very dark sides that I am going to assume we are all familiar with.
I really wonder why you think that the USA should be given a free pass for what it has done in the last decade.
And that's before we get into human rights issues and other 'details'. Comparing yourself to China is not the flex you think it is.
Your bio says that "Farming negative karma is not trolling when you're expressing your honest views." and that's all fine, you have a right to your honest views but if they're indistinguishable from trolling to the point that you feel you need to pre-empt that classification then maybe HN is not the place for you?
I think that one of the reasons for this "popular European sentiment" is the purely emotional one - it's emotionally more affecting when someone who was a close friend starts behaving badly towards you, than when someone who was a colleague with no close relationship remains thus.
The the popular European sentiment is understandable and IMHO correct though. Saying "it's off-putting" is no in way a coherent argument that it's wrong.
