In post WW-II days, young brothers were pimping their at-home sisters to sailors stepping ashore on liberty.
One of the best things America ever did was the Marshall Plan ... to help defeated Axis contries build-up their economies.
I was there.
Men/brothers who would do that and women/sisters who would allow themselves to be used like that didn't need ANY excuse, world wars or whatever, for that behavior. They were pimps and whores to begin with.
Americans weren't starving or in life threatening circumstances, so there was NO need for that to be done. The USO was also in full force "over there" and at home.
My father, mother, uncles, aunts and cousins, etc., were all there too and I never, ever heard that before.
