Airpower vs. Jointness

In the interest of equal time, I link here to a piece by an Air Power advocate who argues for the supremacy of the Air Force at the expense of Jointness. As I am familiar with a cousin of this argument (insert "Seapower" and "U.S. Navy"), it was interesting to read this work  I can't even begin to catalog my disagreements with the logic here, but we could do no better than to start with his assertion that "...wars are always won in the air, never on the ground."  I take a lot of potshots at the Army and land forces, but I am careful never to forget that it is the taking and occupying of the other guy's land and stuff that wins wars, and that is the job of land power.
