The reason Americans aerial power works so well its that they have 6k state of the art planes, logistics and training to use them effectively.
If you had any other country fight the way america does they become broke in a year.
If they expended the same number they spend on planes in artillery they d be trashing a "superpower" like russia pre ukraine even without planes.
Wed probably have by now accurate fire on the move artillery if they had put such an emphasis on that.
And also Tube artillery that can reach up to 100km away and keep on firing for days.
