Govn’t doesn’t know what UAP are, won’t say what they are not

From Legal Insurrection 

UAPs could be:

Airborne Clutter like birds, balloons, or debris

Natural Atmospheric Phenomena like ice crystals or moisture

USG or Industry Development Programs, but they could not confirm “that these systems accounted for any of the UAP reports"

Foreign Adversary Systems from China, Russia, or any other foreign body

As to that other possibility (Roswell-like craft):

Investigators “may require additional scientific knowledge to successfully collect on, analyze and characterize some of them.” (Emphasis added.)

Maybe, just maybe, we or some other country has the electronics and weaponry to bring down one or many UAFs, and all of this sudden talk from the Pentagon is getting us ready for the first dog fight, or the Pentagon is letting another government know we know they know. Not Russia or China, or any European country. They are too busy with remembering who did what to whom in the 19th century. Maybe Israel, or South Korea or Japan. We’ll see.
