Didn’t we outfit our military planes with Chinese parts not to long ago?
Not only parts but the chips in the planes' computers. And we found chips with "backdoors."
I’m sure if we don’t have overt Chinese parts then the we have bootleg parts that some traitor bought that have some Chinese guts inside them. There are programs to built unforgeable part involving things like physically unclonable functions (PUF) but I don’t think we ready for widespread use of those techniques yet.
