I don't think that the US *care* about spies? Look who has been put in charge of the NSA, FBI. There's even someone who is strongly suspected to be a Russian spy working in the Pentagon.

These shipments to China - I remember there being a deal made with the President which allowed these sales to happen contingent on some kind of "risk fee" being paid.. to the President.

The current administration is in bed with Russia so no, they aren’t particularly concerned with those spies
