To emphasize, there's a massive difference between high-end manufacturing which is important for national security, and manufacturing of toys and t-shirts, especially in an economy with a low 4% unemployment. Those low-end manufacturing jobs can't come back to the US, and nor should any attempt be made to make that happen. Any industrial or trade policy that doesn't factor this in is not pareto optimal.
Another thing to point out is that there's no national security justification for bringing back even high-end manufacturing from close allies like Canada.
A good trade and industrial policy is one that tries to protect key industries among allies instead of insisting on every single important industry being done locally.
Well, there are some that absolutely should be done locally. Supply chain risk goes up hugely during time of war. We are very good at protecting shipping lanes but not perfect. Canada is a fine place to leave things as she shares a land border with us; Europe, for some things, is not. Industries needn't be wholly relocated, but at least some level of manufacturing for many of those key areas must remain either in America or very close to us.
