I recall reading that during the 1972 Christmas bombing campaign against Hanoi, the morale of the B52 crews sank to an alltime low due to a perception that they were being asked to pointlessly risk their lives, with some crewmen totally refusing to fly missions. WI this disillusionment with the war among B52 crews had been more chronic and widespread ? How would overall US military morale have suffered to an even greater degree than OTL ? Or, alternatively, what about if such a breakdown of USAF aircrew morale had happened earlier in the VW, such as in 1968/69 after the Tet Offensive, and affected not just B52 men in SAC but also the crews of other major AF combat wings, esp the F4s of the TFWs ? How plausible was an earlier chronic fracturing of USAF morale, as had happened also among the other branches of the armed forces (including in the Marines and among elite Army outfits like the 1st Air Cav) during the course of Op ROLLING THUNDER ?
