“Doesn’t bring any back so that soundbite doesn’t work”
Tariffs on imports from those offshore factories—Hell, let’s call them traitor factories—together with a significant improvement in conditions for business at home will bring them back.
It’s nothing but enlightened self-interest.
Tariffs require Congressional action, at the very least in withdrawing from existing treaties. The President and administrative agencies have only very limited ability to impose tariffs, in reaction to specific violations by either trading partners or firms. Yes, there are violations. But he can't simply declare a tariff on imports from China. It implies a lack of knowledge of the legitimate functions of the legislative and judicial branches.
