An organization called V-Day has launched a campaign to make the world aware of Japan's sexual warcrimes, and ask the Government for an official apology, amongst other things.
Signatures are being collected to be presented to the UN.
As patterns of systematic rape and sexual violence continue today in places of armed conflict such as Sudan, Congo, and Iraq, the importance of recognizing the human rights atrocity committed against women during WWII is a must. This precedent of impunity for wartime sexual violence cannot be tolerated.
