Ah, but there is free U.S. military technology for China. As long as you don't consider the "campaign contributions" to Clinton and Al (Iced Tea) Gore.
What level of tariffs would have prevented China from stealing sensitive technology in exchange for campaign contributions? Pick your metric: all imports, or all imports subject to tariff. LOL
Oh they'll fuss and feud about my comments, but did we help Germany in the years leading up to WW2?
Hell yes, Ford Werks (old man Ford's German division) increased plants all over Germany. Opel (GM's European divison) built more tanks than kraut owned companies.
Donald Douglas and Hamilton Standard/ all the industrialists/ supplied Japan with licensed copies of their latest designs of their aviation products.
(Good money in War ;^)
