Feel like I'm gonna get yelled at for this one but it's not a stretch in this case to say it could impact national security.
Could, certainly. Like, if we were seriously at war and all of a sudden every ammunition factory went on strike that'd be bad for said war. Heck, if it were a real all-out, WWII style war where Rosie the Riveter is encouraging everyone pitch in even small-scale disruptions in the munitions supply chain could cost lives.
But realistically, we're not in that scenario, and won't be any time in the foreseeable future. If the Pentagon ran out of drones tomorrow and all the drone manufacturers went on strike, our national security would still be thoroughly intact. And even more realistically, you know good and well that "for national security purposes" would be used incredibly liberally (word play!). Like how various documents related to Ukraine were classified/redacted "for national security purposes," and then the originals were leaked and it was clear that they were just redacted "because they're very incriminating."
So let's not play around with what's "technically correct" when what's actually going on is incredibly obvious, and thoroughly disgusting.
