SEOUL, South Korea  South Korea has railed for years against the Japanese government’s waffling over how much responsibility it bears for one of the ugliest chapters in its wartime history: the enslavement of women from Korea and elsewhere to work in brothels serving Japan’s imperial army.

Now, a group of former prostitutes in South Korea have accused some of their country’s former leaders of a different kind of abuse: encouraging them to have sex with the American soldiers who protected South Korea from North Korea. They also accuse past South Korean governments, and the United States military, of taking a direct hand in the sex trade from the 1960s through the 1980s, working together to build a testing and treatment system to ensure that prostitutes were disease-free for American troops.

While the women have made no claims that they were coerced into prostitution by South Korean or American officials during those years, they accuse successive Korean governments of hypocrisy in calling for reparations from Japan while refusing to take a hard look at South Korea’s own history.

“Our government was one big pimp for the U.S. military,” one of the women, Kim Ae-ran, 58, said in a recent interview.
