Trump would think Stockdale "Was not a War Hero". Trump only likes heroes that weren't captured.
I'm no fanboy type. I have few "heroes" in my life, not by virtue of knowing few who are or were deserving of that title, but because I have been blessed to know so many.
Some for their military service, my father, who will ever be my hero for many reasons, my grandfathers who carved out their farms with children at their knee, used the timber to build barns and out buildings and a house and prevailed in tough times, others, including my mother, who took on established corruption with little hope of prevailing, but persisted because it was the right thing to do. All had/have the courage to prevail or persist against difficult odds. There have been many I know personally, and few I revere I have not. I have never met Admiral Stockdale, but he is one of the few.
Imho, Trump is not fit to clean the mud off their shoes. Having been blessed by knowing all of them, makes it easy to see what he isn't.
