They couldn't move the entire production to the US today no. It would have to be a gradual ramp up with suppliers coming online in tandem with the increase in production. There's no supply here because there is no market here, but if you build it they will come. It's not like it's impossible for an existing company to start up a specialized screw line, or for some startup to appear to fill the demand. It's a slow and painful process, but it's not like the Chinese manufacturing industry sprang up overnight either.
The real question is if the pain of switching over is worth it. Do these extraordinary costs in security and shipping outweigh the increased labor costs and potential for unionization in the US? Trump's tariffs might actually affect this calculation as well, but their long term stability is questionable, especially if you're looking 10 years out past the end of his term.
