Bill, I had not seen what he said, but I talk to a lot of military and ex-miltary on the net. A number of them are making or quoting similar comments. Air power enthusiasts have been claiming for a hundred years or so that aircraft can win wars by themselves. I think some people are claiming that Bill Clintons bombing in Serbia ended that conflict. The claim is disputed, and even if true its the only time it happened.
I agree, its going to take "boots on the ground."
