Use F22s to clear the skies. A10s are tough, but use cruise missiles and other platforms to clear the SAMs. Then use A10s and B52s (yup, those old busses) to clear the ground.
This isn’t that complicated.
The F35 is a fine aircraft. However in Iraq my son's best friend was an A-10 or Apache. As an infantry man they knew if it all went to Sh-t, those boys could bring in close and accurate support from the air.
The only problem with the A-10 is it does not have United States Army painted on it!
The F35 can not do what an A-10 can nor can an A-10 do what an F35 can. They both have different missions and different capabilities. We need both.
