Most protectionists howl "national security" when stuck with a pin. They do it so often, in fact, that I fear the next time a real national security concern is raised, no one will listen.
You've got it turned around. And as the failures of CFIUS have proved...its the enemies of national security who howl "protectionists" when someone properly notes a concern. They have never listened. And Treasury, Commerce, the Feds, State etc. wouldn't know a
real national security concern...any more than Tim Kane would.
You should read up on the facts. But of course, you wouldn't believe the Defense Sciences Board.
Or its Reports Here, here and here.
