The French hated Germany, &so did the Belgians. But, even before the dust settled a very large portion of the US soldiers and civilians were rethinking the whole mess. There was a significant degree of sympathy in the US for the German citizens and support for the Red Cross efforts to relieve the winter hunger was widespread in the US. The Italians did not hate Germany at all. Many had been guest workers there pre 1914 & were wondering why hey had been at war with Germany in the first place. Even the Brit voters were a bit disgusted with the wartime propaganda & the 'hate' was subsiding. The legitimate hate of the Germans derived from the abuse of the Belgian & French civilians in the occupied provinces. Doubling down on that sort of abuse by expelling several million women and children from their homes and turning them into impoverished refugees shuffling across the Rhine river bridges has a certain degree of moral hazard. Note that when the French sent a few regiments into the Rhineland five years later to collect a late reparations payment they had zero support from the US & Italy, & the weakest of support from Britain.
