A belief that the U.S. should be more self-sufficient,...
I agree with this bit. When we can't get N95 masks because they're all made in China, and the Chinese are using them for their pandemic...that's a problem.
...less engaged economically with other countries,...
Totally disagree with this. Engagement is beneficial on so many levels, not just the basic exchange of goods. Like ancient times when one kingdom would send a princess to marry the prince of another kingdom. It fosters unity, and a less likelihood of warfare. Trading for stuff you don't have and/or can't produce is great, but that's just the obvious bit.
I would be speculating here, but perhaps his talk of tariffs is in lieu of advocating a colonial empire (which he sort of is doing anyway, with talk of taking Greenland). Colonial empires don't need trade as much, because they've seized the resources they need.
