Whether you agree with tariffs or not (I think the *tariffs are always bad* perspectives are somewhat myopic), there are some things that have not been discussed widely that I found particularly questionable. 

- The EU is demoted to a third party for the US. It is no longer an ally and will be treated the same as adversaries when it comes to trade. The game theory case against the EU is much harder to make than against China. 
- The accounting for this is HIGHLY selective and intellectually misleading. The US has been flourishing economically in the last decade compared to EU member states. This is also because the US has been leading in software and digital services.  Adjust for (digital) services and the trade deficit between the EU and the US shrinks to merely 50B USD. But what if we take other costs into account? The EU also has to bear the majority of cost for migration (both in terms of climate but also conflicts) even though arguably both parties participated in the creation of the problem.

If we consider everything instead of cherrypicking parts, the relationship between the US and the EU strikes me as equally beneficial. 

The idea of extracting the maximum value from certain parts of the relationship will without a doubt lead to questioning of the relationship in its entirety.
