No, it is indeed Europe vs. USA — we have no choice but to face the new realities the current Trump administration created. The tariffs will come, regardless of how many US citizens oppose them. The grab to Greenland and Canada is also very real and is not changed by the opinion of Trump‘s opponents.

We have to fight back, if we want it or not.

I say explicitly could harm. Sanctions work the best when they hit as hard and fast as possible. See how for example Russia was able to adapt their war economy to rounds of sanctions because they came in so slow. So the harder the boycott, including all US businesses as much as possible, the faster even the magats get restless with that joke of an administration.

The "nationalism comes in different flavors" argument feels very enlightened centrist to me when at the moment it's every authoritarian regime (china, russia, us musk adminstration) against the one bloc that cares about democracy.
