yes, this story has some up before - during the ports deal, this was on the CFIUS list too.
again, if CFIUS was doing its job - what it would be doing here is asking DoD if this company was a sole source supplier for critical components, what those components were, where they came from, whether they could be replaced by an alternative. just for starters.
the US is going to have problems in this area shortly (generally), with respect to semiconductors. so much of it is moving to china, that at some point, DoD is going to have to maintain portions of it as a "cottage industry" in the US - unless we all feel comfortable that without chinese parts, we can't build planes or missiles or laser guided munitions.
Isn't DoD already represented at CFIUS?
