My Father was in Finland when the war ended. He was taken POW by the English who he said treated them very well. On the way home they were handed over to the Americans who stole most of what they had and made them sleep in the dirt and generally treated very badly. Not a solid foundation for love. Living amongst Canadians and later amongst Americans.
People are people everywhere.
Once you get to know a people the hatred disappears pretty fast. The curious thing was that I hated the English more than anything. But 4 years in School under the Germans did that. That's all we heard every day. That hatred lasted for a long time until I realized one day that it was probably the brainwashing that was at fault.
