Bringing tariffs down in the past literally took decades. Politically it’s very hard, because the benefits of trade go to everyone and the benefits of tariffs go to special interests. As a rule, special interests tend to win out.

Because it’s arbitrary discrimination against their exporters. This is putting aside the forced purchases and investments Trump is demanding of various countries.

All these TACO memes are wearing pretty thin. Trump has instituted a minimum of 10% tariffs on all trading partners, with scant prospect of them ever lowering in the future even after his presidency (once tariffs go up, it’s very hard to bring them down because of the special interests that come to depend on them). He has strongarmed the EU, Japan, and other countries into accepting these permanently elevated tariff levels without retaliation. Only 3 countries have shown any sort of backbone against this: China, Canada, and Brazil (maybe India, but it’s too soon to say). In all the other cases, Trump ain’t the one chickening out, it’s the other side that abjectly folded.

(It doesn’t matter, by the way, if the Europeans intend to slow walk the investments and weapon purchases they promised to Trump, or whatever. That’s copium. The point is that they bent to Trump’s will, and once you cave to a bully, he’ll be back for more.)
