I don't think this person understands that the US CANNOT build borders around trade ...of this magnitude.  Bullying companies is NOT the way to manage trade and in the long run will damage hugely the US economy, not to mention global ramifications.  Isolationism did not work with respect to WWII, and it won't work in the global economy......IF he wants to promote this kind of thing, don't penalize them for building elsewhere.....give them incentives to build locally......but that may violate NAFTA..... NEGOTIATED contract...not that this man cares about ethics.....if/when he tries to renegotiate, he will find he "may" be out of his league.  He is not a KING, he is a temporary leader of the US.
