That’s scary. Here’s something a little more scary: the large raw materials (iron/steel) foundries are all about gone in America. We rely on imports even for US based manufacturing. Our manufacturing Achilles heal is a supply chain that begin in China and other places abroad.
Imagine if we set it up in the 1920s that we were reliant on Japan for everything, like we are with China. We didn’t become enemies until the mid-1930s.
