The scenario these address aren't two nation states going to war, one with eagles and the other with drones. The scenario is the once-per-decade terrorist attack, in which case losing an eagle or two to mitigate the attack is worthwhile.
Was this as weird to type as it was to envision?
That's the same scenario I'm talking about. Overpowering the input signals is a proven, scalable defense that can be easily deployed to police forces, stadiums, national monuments across the world and for minimal cost. You simply will not be able to do that with a highly trained eagle.
