And it's wrong for national security.

We need to retain some presence in various industries because we cannot rely on foreign producers in a 'crunch'. For example, masks. Most disposable masks were made in Asia. During COVID those nations hoarded them for themselves (of course!). So we had a shortage in this country for months.

We need steel. How much military hardware is made -at least in part- from steel? (Hint: a lot)

We need domestic supplies of electronics components, steel, copper (pretty much any metal you can name), glass, polycarbonate, etc. Almost anything you can think of. If we end up in a conflict with China (which is getting more likely every day), we can't be relying on things that are "made in China", or even Taiwan (too close to China, supply lines could be disrupted).

It's critical that we maintain a domestic source for pretty much everything.
