I don't see how there is going to be a market built (we are talking about a five or ten year timespan here to build a semiconductor factory) around a trade barrier created by a tariff where nobody knows how long it will be in effect. Would you bet dozens of millions of dollars to create a production of already existing, cheaper produced products to supply a market created by tariffs? How easy would it for the next administration (or the current) to drop these tariffs? What about your investment then?

Which sane person would make such an investment?
