I just figured he was known as a guy who was a blunt and forceful individual who felt fighters should be king, not bombers (I'm not sure how much finesse he had). That said, if I recall, he was pretty astute about matters regarding Asia, as was Admiral Richardson."Chennault is an egotistical maverick alarmist, and obsessed with the Orient!"
I don't think he felt they could walk on water, so much, as he was concerned of what they could do to us."He thinks the Japs can walk on water."
Because they were ignoring anybody who said otherwise..."Everybody knows those little yellow monkeys with their coke bottle glasses and their wood and fabric biplanes can't build a modern warplane!"
Not at first, anyway..."If we wind up fighting the little yellow bastards, we'll have the biggest turkey shoot we've ever seen!"
