I could be wrong, but I believe all the videos we've seen were leaked first, then acknowledged. That alone suggests the military has something to hide

Since they've already been leaked, the best US can do is try to deflect. Release the footage to "prove" you aren't hiding anything, then claim you have no idea what it is.

All very tinfoily. But we know something is out there. We just don't know who made it

I dont mean why release the videos, I mean why swarm navy warships.

From what I remember from LOTS of movies from the 80s, UFOs where always after the US military because they have stolen some advanced tech (their ship / engines to get back home), or because they have alien prisoners.

just saying
