Seems to me it did pretty well in Aghanistan and the capture of Iraq. Remember Shock and Awe?
Made up for precisely what we DON'T have in sufficient numbers: Boots on the ground.
Absent the air power, the US ground forces would have been in seriously adverse fights.
Now in the glow of victory, the actual basis of those victories is going down the memory hole...as the temporary expediencies of the moment demand short-sighted political squeaky-wheel greasing.
And let me tell you, there is no ground role for a fight against the Red Chinese. And that fight is coming and SOON.
We need to keep that fight purely at sea and in the air.
No role whatsoever for any ground pounders.
