Final answer:
Kurt's statement reflects a discrepancy between the expected image of a Nazi derived from wartime propaganda and the reality that those fighting in the ranks might just be ordinary individuals caught in a conflict.
Step-by-step explanation:
When Kurt says, "It seems we fought a war against the Nazis, but I haven't met a Nazi yet" (p. 221), he is likely expressing a sentiment that despite being part of a conflict against the Nazis, he has not encountered individuals who neatly fit the villainous stereotype of a Nazi soldier that might be expected given the propaganda and rhetoric of the time.
This statement can reflect on the notion that enemy combatants are often dehumanized and vilified to justify warfare but, when faced with the reality, one finds ordinary individuals caught up in the machinery of war.
It could also imply an understanding that many who served in the armed forces might not have personally held extreme Nazi ideologies but were instead regular soldiers fighting for their country.
