I can explain it.

I'd like my critical supply chains to be in North America. Ideally, I'd have a free trade zone with Mexico and Canada. Tariffs, two-sided, reduce trade, and bring me closer to that reality. I'm okay paying slightly more for that security.

I'd like the same thing in the EU too, and in other major world blocks.

There's a slight efficiency gain from specialization, where each country brings a skillset, but it's totally not worth it to me versus the brittleness which comes with it.

Remember how the Covid supply chain disruptions cascaded? That's a tiny fraction of a really bad natural disaster.
