"We send them critical defense manufacturers now?"
According to this article...no.
Here's what I can deduce from the content of the article:
1. A company named Magnequench sold off equipment from its factory in Valparaiso, Indiana about 2.25 years ago.
2. Magnequench had a contract to make certain components of the Joint Direct Attack Munition.
What I am unable to find is any smoking gun saying that the Valparaiso plant actually made JDAM components.
There's a lot of heated rhetoric in this article; there are precious few facts, and those facts do not seem to be related to each other. It is, to quote Shakespeare, "much sound and fury, signifying nothing."
See post 23. The info is dated, but there was and is clear concern that harmful tech transfers were possible.
