Abe's political need behind deal with ROK

Japan has agreed to pay 1 billion yen ($8.3 million) to help the Republic of Korea set up a fund to support Korean women forced into sexual slavery by the Japanese army before and during World War II, in order to settle the "comfort women" issue.

Later, during his talks with ROK President Park Geun-hye over the phone, Japanese Prime Minister Shinzo Abe said the deal was "final and irreversible" and rendered apology to the Korean women who were forcibly "recruited" as sex slaves. Park, on her part, said she expected the agreement to help develop bilateral relations in a stable manner with an eye to the future.

For many, it is surprising to see the sudden settlement of the sore point in Tokyo-Seoul relations, although some uncertainties remain. To begin with, the deal is actually a compromise between Japan and the ROK in which the United States seems to have played a vital role. US Secretary of State John Kerry welcomed the agreement on the very day it was announced, saying it "will promote healing and help to improve relations between two of the US' most important allies". Applauding the leaders of the two countries "for having the courage and vision to reach this agreement", he even urged the international community to support it.
