The point appeared to be that there is nothing else on Earth as sexy, unstoppable, and totally cool as a young American paramilitary adventurer confronting nasty Asian villains, Commies, and other such swarthy foreign types and besting them in personal combat as only a two-fisted Yank can...

The English had their heroes along that line too. Jungle Jim Bradley comes to mind. He too spent much of his time defeating sinister Asians and Communists in the steaming jungles. He also had a Native Malay sidekick named "Kolu". Kolu was a good Native. He may have been very distantly related to Tonto, but I'm not sure about that.
