The Netherlands was never hit that hard by the Nazis, the invasion was over in a few days and probaly cost less lifes then the actual retaking of the country.

Also important to remember is that Dutch people consist for a good part of the so called "germanic/(Arien?)". So non Jewish Dutch people did not suffer that heavily from the Germans, except the "hongerwinter" of 1944 in which the Northern part of the country was still in German hands while the South was freeded and thousands of people died from the extreme winter and hunger because the Germans took everything they could use for the war.

In the retaking of the Netherlands by the Allied forces a whole island was flooded by bombing the dykes, because the German defences were to strong. The most bombed city in the Netherlands is not Rotterdam which was destroyed to forces the surrender in 1940 by the Germans, but Vlissingen, a city which is a strategic point to prevent ships entering the Harbor of Antwerp and was heavily defended by the Atlantic Wall.
