I will see if I can find a source but

My father who works high up in a military tech company.

They build as much as they can in China (without losing US contracts) then bring it to Canada to finish the parts they can’t do in China before moving it to the US to assemble and put a “made in USA” sticker on it

For me; the company I’m at gets all of our metals from China because it’s so much cheaper to ship it here
