I feel like at any kind of scale this would be an incredibly slow type of strategy. An F22 could have been used because initially the DoD had no idea what the thing was and if it was hostile, but as time goes on I really doubt that deploying F22s would continue to be the American strategy. The irony of this strategy is that the US absolutely LVOES to spend money and resources on defense, so this isn't exactly hitting 'em where it hurts.
