"Direct mention is made of the possibility that UFOs could be highly advanced Russian or Chinese technology."

This is patently jingoist. The suggestion of a "possibility" of something is made only for distraction and fear mongering.

"UFOs "pose a hazard to safety of flight" and could be a national security threat."

There is absolutely no evidence to support this statement, anymore than there was for Russiagate or Syrian Chemical Weapons attacks. It is just made up for propaganda purposed.
