Tariffs are a two-way street.
We slap tariffs on other countries products and they slap them on our products. The result being that we export nothing. That's hardly desirable.
Economically we need to have Europe and Asia bombed all to h3ll again while we remain unscathed, then we can manufacture all the products and sell to them.
Tariffs cannot replicate that.

It is frequently stated that US postwar prosperity came from our competitors being destroyed in WW2, but this is not accurate. The easiest and most obvious reason is that although the main competitors for our manufactured goods lost their ability to produce them, the main customers for our manufactured goods also lost the ability to buy them.
