@Chazman: you are defining victory by your own criteria. It does not work that way. Not for the people in the region, and not even for Donald Trump who himself defined his objectives by "unconditional capitulation".
Not sure victory is recalling a carrier from the Pacific given the tensions there...
As for military morale it is low if we listen to the families instead of the pundits and that shouls not suprise anyone: it is always a challenge in long deployments.
Their professionalism is not in question, it's that their efforts may feel wasted by the strange outcome...and that does not help morale.
