RH200,
I think we agree.
I'm sure that Air Power proponents have been saying we'll be fighting Air Forces for decades but it's never happened. I personally doubt we'll see high end air-to-air combat in our life times. We use fixed wing day in and out for strike and ISR, but we throw millions of pounds of fuel and millions of hours training for air-to-air which doesn't seem to have happened or be likely to happen.
That being said, I do think, as the most stressing case we need an insurance policy against it. I'm just personally convinced the likelihood is tiny.
