Americans used 'comfort women'

CNN/AP story about how American soldiers allowed the comfort women system to continue, and took advantage of it despite having some evidence that the women were coerced into prostitution.

"Sadly, we police had to set up sexual comfort stations for the occupation
troops," recounts the official history of the Ibaraki Prefectural Police
Department, whose jurisdiction is just northeast of Tokyo. "The strategy was,
through the special work of experienced women, to create a breakwater to protect
regular women and girls."

MacArthur stopped the practice in spring 1946. Story here.
