The erection of this statue is sheer hypocrisy on the part of Germany and does nothing to achieve that end.
The statue was not erected by Germany. It's not an endeavour by any German authorities and its purpose is not to lecture Japan or anyone else in some sort of finger-pointing exercise.
The article linked to by the OP makes that abundantly clear.
The statue was gifted to the city of Berlin following work by the Korea Verband, an organisation which seeks to promote Korean culture, teach Korean history and further good relations between the Korean people and the German people.
The actual statue was created by two Korean artists and gifted by the Korean Council for Justice and Remembrance for the Issues of Military Sexual Slavery by Japan. Such statues were also gifted by this NGO to Australia, Canada and the US.
Its purpose is twofold:
- to raise awareness of the 200,000 women from 14 nations who were held in sexual slavery by Japan during WWII, who still have received neither acknowledgment of the injustice and pain they suffered nor apology from Japan and
- to condemn sexual violence used against all women in war, wherever it happens, but especially government sanctioned atrocities of this kind. Which all nations, including Germany, engaged in throughout history.
As a result of the campaign by surviving Comfort Women, like those active in the Korean Council I mentioned above, the crime of holding women in sexual slavery as a wartime tactic has now been recognised as a human rights violation and a war crime at international level.
Oh, and just to add, the statue has not been removed today. The matter has been referred to the local court and until the verdict is delivered, the statue will remain where it is.
