The Dutch committed many war crimes and have had a very hard time admitting to them, in part because that part of history wasn't exactly taught in school and in part because it also requires admitting that the reason we are such a rich country is because we were good at trading, but mostly because we were good at stealing and slavery.
I think it will take until the Royal family will finally be thrown out for the last of the (very efficient) propaganda machine to be shut down and then we can really deal with this. Likely the Oranjes will end up forfeiting their fortune as part of a reparations deal or something like that. It makes perfect sense, they personally, more than anybody else profited from these atrocities and they were the first ones to flee the country during the war.
