International Holocaust Remembrance Day

In April 1980 I flew EL-AL to Tel Aviv. It was Holocaust Remembrance Day.
No, it hasn't moved, it's just that the original one isn't International.
International Holocaust Remembrance Day has been running for only ten years. 
For sixty years the world forgot about the 5 million non-Jewish victims and left the Jewish people to remember their own.
Despicable.
