> retaliation would mean more anti-US people selecting themselves into these projects.

Very few people are martyrs or want to become martyrs. Even fewer in places where life is generally fine and for a cause that isn't dire to their loved ones.

The curve of willingness to oppose aggressive action rises significantly before it drops off at some safety threshold. I believe US-Europe relations are still well below that threshold and the rise in level of aggression is only stirring up more resistance, not less.

I think you highlighted something without meaning to. The core problem is that short of literally nuking Brussels I don't think the EU will ever think the threshold was crossed. Even then I'm not sure. The US has threatened to invade sovereign EU territory multiple times this week alone and we're still having this chat here. The US will keep pushing because the EU does basically nothing when it's literally threatened with invasion.
