That's true of some products, not all of them, or even a majority. And even for those products, well, if it's going to take a long time then we better get started.
> And there are a fair number of raw materials we just don't have
This is again not the common case, and even then it's not necessarily the wrong solution. For example, China currently dominates the production of rare earths and the US doesn't have sufficient reserves, but Australia does, so higher tariffs on China than Australia create an incentive to move mining operations to Australia which breaks China's lock, and creates the incentive to invest in rare earth processing in the US, since then you're only paying the (lower) tariff on the (lower-priced) raw materials rather than the (higher-priced) refined product.
> Trump isn't applying tariffs in a strategic manner to get domestic manufacturing to come back.
This is more of a Trump problem than a tariff problem. If you do something wrongly enough it obviously doesn't work as well as it otherwise might.

There are "sufficient reserves" (known rare earths in the ground) across the globe and the US absolutely has large reserves.
> to move mining operations to Australia which breaks China's lock
There are already mining operations in Australia delivering raw concentrates in bulk to China. Again, not a shortage of mining operations or a shortage of reserves in the ground.
It's the concentrate processing that China invested time and capital in decades past - every other country about the globe (save for Malaysia, to their regret) figured they'd leave the acres of acid ponds and low level radioactive waste to the Chinese.
Now the US wants Australia to take that on, and that's a deal with the devil for Oz while the current POTUS cannot be trusted to hold up any deal.
