Taking these at face value, I find them worrisome, and would think that the IC would be paying more attention and that warfighters/policymakers would be banging down the IC’s door for answers.
For reference, as you no doubt know, the IC published a handful of articles about UBL/al Qaeda prior to the 9/11 attacks, and it was still the IC’s worst failure - necessitating a big Congressional commission and a report with big cultural changes.
Then the IC got it wrong on Iraq WMD (HUMINT source ‘Curveball’), another failure, precipitating even more scrutiny, Congressional hearings, reports, and culuture/org changes.
So if there is some advanced threat out there that the IC is either ignoring or knows about but is failing to adequately investigate, then we are at risk of another failure to warn - which I think would be a bigger deal than 9/11 or Iraq WMD. As deadly as those enemies were, neither of them operated advanced aircraft that could exceed the capabilities of our 4th gen fighters in terms of speed, maneuverability, radar jamming, etc. We were never at risk of completely losing air superiority in the AO.
And if the anomaly is, as you suggest, possibly a wacky new US technology that we decided to red team against our own fleet without telling them... then why is CDR Fravor out there giving so many interviews, and why are the NY Times and DoD press website releasing videos and statements to publicize the capability gaps exposed by the red team’s apparent success?
