Where have we heard warnings about this potential situation before? You know where our machine tools come from? China, of course. This Uke quagmire gets more ridiculous with each passing day.
About half of US machine tool purchases are from domestic manufacturers actually. The US does make machine tools. Some of that has recently been from foreign companies setting up US manufacturing.
As for imports, IIRC China supplies about 1/4, Germany maybe 1/5 of imports.
China itself is also the worlds largest importer of machine tools. I think its also a net importer.
Machine tools are a very hot business right now.
