Boyd was a genius in some areas, but he was stuck in the tactical world of 1955. And whenever our planes have gone up against Soviet planes, we've kicked ass.
I would suggest you read (or re-read) the various books available on Boyd.
He was a tactical genius, in that he taught himself how to get the maximum capabilities of our aircraft ...inspite of design limitations.
He became an Aerodynamics expert who was instrumental in changing/improving aircraft acquisition to get a very capable (and much lower cost) F-16 fighter aircraft.
Later on - he became the latest “global thinker” on the same level as Sun-Tzu, Machiavelli, Clausewitz, etc., in maneuver tactics. His OODA loop was used ...from the individual fighter dog-fight, to the larger battle field ...to the global strategic picture.
If you claim Col Boyd was stuck in the 1950’s - you don’t know Boyd! For example - he was called in as an advisor prior to the Desert Storm attack to kick Saddam’s military out of Kuwait ...based on his global thinking/strategic capabilities! The Marines consider him to be one of the major thinkers of the 20th Century for tactical planning.
