Devil is in the details. So how does Trump propose to make this “force” happen? Carrot or Stick?
All he has to do, is call someone at Apple. Even their janitors know Apple builds it's computers in the U.S.A., practically the only large computer maker that does so. Once Trump calls and finds out, he'll claim he got it done.
Apple has built computers and chips at factories in California and Texas. As well as many other components throughout America. Trump would do well to investigate HP, Microsoft, and other tech companies who build in China.
