The French had sufficient fighters and other combat aircraftto gain air superiority and conduct close air support against the AFV (Armored Fighting Vehicles). The simply failed to organize and deploy enough pilots, command and control capabilities, and combat support to make these aircraft effective in the battlespaces.
This is truly a cautionary tale for the present day U.S. Air Force and U.S. Naval Air Force. As the Germans learned in Big Week 1944 and the French learned in May-June 1940, the current shortage of combat pilots and flight time for proficiency training and maintenance results in the loss of air supremacy and air superiority with catastrophic consequences for naval surface forces and Army ground forces. The Carter, Clinton, and Obama Administrations have been quite effective at destroying more of the American air forces than all of the hostile combat actions combined, excepting the Truman disarmament post-WWII.
Which military in the world do you believe poses an air superiority threat to USA?
Military capabilities are of themselves unimportant. They only take on meaning in comparison to the opposition.
