If you don’t support tariffs to bring back manufacturing jobs domestically, how do you think we could make it through a war with our manufacturing partners?
I express no position here about China nor Taiwan, but the false dichotomy presented is between: 1) enforce trade barriers indiscriminately against every country, territory, and uninhabitable island in the world without regard for allies nor enemies, or 2) diversify economic dependency away from one particular country.
The former is rooted in lunacy and harkens back to the mercantilism era, where every country sought to bring more gold back home and export more stuff and reducing imports. The latter is pragmatic and diplomatic, creating new allies (economically and probably militarily) and is compatible with modern global economic notions like comparative advantage, where some countries are simply better at producing a given product (eg Swiss watches) so that other countries can focus on their own specialization (eg American-educated computer scientists).
As a specific example, see Mexico, which under NAFTA and USMCA stood to be America's new and rising manufacturing comrade. Mexico has the necessary geographical connectivity and transportation links to the mainland USA, its own diverse economy, relatively cheap labor, timezones and culture that make for easier business dealings than cross-Pacific, and overall was very receptive to the idea of taking a share of the pie from China.
Long-term thinking would be to commit to this strategic position, this changing the domestic focus to: 1) replace China with North America suppliers for certain manufactured goods, 2) continue to foster industries which are "offshore-proof", such as small businesses that simply have to exist locally or industries whose products remain super-expensive or hazrdous to ship (eg lithium ion batteries). Sadly, the USA has not done this.
It is sheer arrogance to believe that the economic tide for industries of yore (eg plastic goods, combustion motor vehicles, call centers) can be substantially turned around in even a decade, when that transition away from domestic manufacturing took decades to occur. Further egoism is expressed by unilateral tarrif decisions that don't pass muster logically nor arithmetically.
