Japan admitted the Imperial Army ordered the building of these brothels and the trafficking of the women. And now that it's been 70 years, there are only 46 remaining comfort women still alive in South Korea. So also in this deal, Japan is going to pay 1 billion yen - that's about 8 million U.S. dollars - to provide social services and health care to the surviving victims.

South Korea are pushing for a stronger way to isolate and punish North Korea for its latest nuclear test.

U.S. has certainly been wanting this to happen since both Japan and Korea are longtime allies of the U.S. and this estranged relationship has prevented better cooperation.

The first comfort women didn't actually come forward until 1992, and since then, the issue has really been kicked up. Japan issued a 1993 acknowledgement on this. It's called the Kono Agreement. But in recent years, South Korea has been wanting an apology to go much further.

In South Korea, there's a lot of folks who are already saying this deal doesn't go far enough. And I had one source say that President Park will, quote, "get lots of love from D.C. for this" but that the money itself for the fund - $8 million - isn't that much and that the deal itself doesn't ensure that future generations will learn from history so not to repeat it.

And that said, this [issues of comfort women] is important for reopening a conversation in both Japan and in Korea and on their respective understandings of history. Policymakers are going to be trumpeting this deal, but you know, as of now, we just don't know whether the women themselves who are actually victims will think this agreement is enough.

North Korea has certainly, in the past, used detainees to initiate diplomatic exchanges with the United States.
