Which is just one of the ways in which a simplistic view of trade, like our current administration seems to have, is grotesquely out of tune with reality.
The entire cultural perspective on the auto industry in the USA is based on the experience of what economic historians now call the "magic economy," those few decades after WWII where Detroit had, in effect, a captive market, a virtual monopoly, and because of massive profits the ability to accept an unprecedented level of blue-collar labor compensation and benefits. The whole thing was artificial as hell, and when any thing disrupted the magic--OPEC, globalization, environmental issues, whatever--the entire house of cards came crashing down.
Kudos to Detroit for finally getting their shit together after some really tough times (mostly self inflicted) and making, now, competitive products. But their problems today are not pernicious foreigners, it's still their own legacy demons they are fighting as well as the rapidly changing consumer landscape. Detroit automakers were never good at shifting gears (hah!) because, for decades, they simply didn't have to. The Japanese and Germans and now Koreans, though, are much more used to changing their tactics and approaches, though some of the old guard here (Toyota, Honda) eventually became so successful they, too, started to show signs of stodginess.
