Important to remember the difference between nations and civilians that had been brutalized and occupied by the Nazis for years versus Germans who had mostly lived well (outside most large cities, German towns and villages were almost untouched). The Dutch, for instance, had a serious famine in winter 1944 and 1945 in a big part of the country and many were literally starving upon liberation. The French had lived through occupation and chronic looting, shortages, hunger, and forced labor. Even where the Germans weren’t killing, they were pillaging and making sure that the Reich stayed as comfortable as possible off the wealth and labor of their occupied zones. And of course, the Germans wanted very badly to get on good terms with the Western Allies because they understood what was coming from the East.
When you read memoirs of Soviet (and to a lesser extent, British/American) soldiers, you note how astonished they were to find prosperous, comfortable, civilized farms and homes set in little fairy-tale forests and villages. The average German farmer had wealth and comforts beyond what any Soviet soldier could fathom, right up till the end of the war. Americans were more likely to succumb to the extensive charms of liberated Germany while the Soviets were whipped into a fury upon seeing first-hand that this wealthy and happy nation living off the fat of the land came to benighted Ukraine and Belarus and Russia to rob and steal from people far poorer.
The Dutch, French, Belgians, etc. weren’t “themselves” as a nation at all and then you add in the tension in every war like this where the liberators feel some anger at the conquered for allowing themselves to fall while the liberated chafe at the idea that they’re supposed to feel gratitude and happiness after years of brutality and it gets toxic, the straightforward “victor/loser”’ dynamic is easier to grapple with especially when the loss came quickly and the victors are well-behaved.
