Basically the amount of leaked material and testimony is forcing the DoD, via direction from Congress and a court order, to produce an unclassified report. They don't want to produce anything, they are being compelled to.
I don't expect that an unclassified report would reveal any conclusions. It will simply document the events around the leaked material, confirm that the events occurred and maybe offer up an additional encounter or two. They will emphasize that being unable to identify aerial objects and claiming aliens is a giant leap of logic and not appropriate.
And they are right, particularly since they already know that the origins of UAPs are not alien and they will likely never disclose what they do know. Its more culturally shattering than aliens.
I find the logic and decision flow so ridiculously obvious that I'm always surprised that it is almost non-existent in our culture as an idea. But not totally non-existent. A guy named Mac Tonnies codified the idea in something called the Terrestrial Hypothesis (or the Crypto-terrestrial Hypothesis) and it is so beautifully elegant, logical and simple that I will be surprised if it isn't the case.
Short version... something got smart before us. That something may have figured out that life on Earth's surface was a losing proposition, eventually surface dwellers get reset back to primitive conditions by all the various surface calamities like asteroids, comets, volcanism, ice ages, coronal mass ejections, gamma rays bursts, pole reversals etc. So maybe they dug in deep, maybe eventually they discovered geothermal energy. But more importantly maybe they advanced technologically in a smooth uninterrupted way unlike our sputtering development between total collapses.
What is more likely? Something travelled across interstellar space or something got smart here on Earth, the only known progenitor of life in the observable universe.
If they are 1000 years ahead of us we have a slight problem. If they are 1 million years ahead of us they won't likely even deem to communicate with us aside from some aerial displays.
