Notice how they bleep the words “Jap” or “Japs” in most showings? Not that I like derogatory terms but leaving the words in would be an accurate description of the sentiments of that time. PC run amok again.
My Dad fought the Japanese in WWII at Attu, Aleutian Islands, Alaska. It was 20- 30 below and most of the Army still had summer uniforms.
Till his dying day they were all Japs.
