With things like these I think it's helpful to look at what is being done, not just what is being said. In line with the provisions of Senate Report 116-233, accompanying the IAA for FY 2021, the UAPTF’s long-term goal is to widen the scope of its work to include additional UAP events documented by a broader swath of USG personnel and technical systems in its analysis. As the dataset increases, the UAPTF’s ability to employ data analytics to detect trends will also improve. The initial focus will be to employ artificial intelligence/machine learning algorithms to cluster and recognize similarities and patterns in features of the data points. Maybe leaning into the aliens angle a little bit is just a way to get funding for this type of thing. "AI surveillance grid" is probably a bit of a hard sell to congress without the added threat implications. That said, if it really is aliens, you'd probably want this same kind of technology all the same, so it doesn't strictly rule anything out. Overall I have to say I'm undecided for the moment, but it certainly is interesting. If I'm going to speculate though, I think the most likely scenario is there is some really advanced capabilities in the US arsenal, and this is a pre-emptive measure to anticipate adversaries playing catch up. If you have craft that can do what is being asserted, or even just a healthy fraction of those capabilities, it really becomes an information and surveillance game.
