Answer:
So that the Dutch people would always remember the Nazi occupation and learn from their history.
Step-by-step explanation:
Nazi Germany invaded a neutral Netherlands in World War II on 10 May 1940, and initially ruled them with a velvet glove but later changed their stance and started persecuting Dutch Jews, hunting and killing them.
The Germans increased the tax they demanded from Netherlands as the war intensified which made standard of living in Netherlands drop drastically. There were pockets of local resistance to the Nazi occupation which later increased.
After the war when Germany was defeated, the Dutch launched operation Black Tulip and deported every person with a German passport and tried people suspected of helping the Nazis.
This is the history the Dutch minister of education is keen for the Dutch people not to forget.
