The Trump admin let S. Korea buy the American nuclear submarine platform (that they can customize for their use but can't touch the nuclear propulsion part) because Japan wants it more and now will pay whatever the U.S. asks to maintain the current balance of power in the region. Let the one with less money buy a Ford Escape at a relatively lower price because that will make the one with more money panic and buy insanely marked-up Lincoln Navigator with all sorts of unneeded options. I feel like Steven Miller figured this out, not Trump.
