I might as well go full NSFW here–well, not me, but this site which details WWII sexual psyops. The various countries embroiled in WWII used (or tried to use) sexual suggestions to demoralize enemy troops.
This site details the perversion, the anti-semitism, and the psychology used on your (great?)grand-parents to get them to surrender or turn back. In this day of “2 girls 1 cup” (never seen it, thanks) these pictures seem positively quaint, but they’re not all blurred out so beVARE (as Bela Lugosi would say).
Interestingly, the author’s thesis is that these psychological attacks had the reverse effect. The men would use the naked girl pictures as pin-ups. This tells you something very basic and true about beauty, if true. The picture–the promise of beauty, love and sex–completely overrides any text.
In the soldier’s mind, it’s the girl he’s fighting for. And since she’s in his mind, he’s not likely to believe any of your libelous statements about her. She’s Rita Hayworth in The Strawberry Blonde or Lauren Bacall in To Have and Have Not or maybe even Judy Garland in Love Finds Andy Hardy.
You’re likely to just make him mad by suggesting anything else.
