i cannot see how the US has no/fewer/lower tariffs than their trading partners. here are some numbers for US-EU trade: https://www.statista.com/statistics/547412/average-eu-and-us...
and here's an article arguing why there's no US-EU trade deficit, in German, though: http://www.sueddeutsche.de/wirtschaft/handelsstreit-usa-eu-h...
what they argue for: sure, looking at goods, there's a deficit for the US. But once you take services and primary and secondary income into account, then the US actually cuts the better deal with the EU.
imv, trump/the current US gov are twisting the numbers to get a better deal.
