Oh my, I don't think anyone's trying to defend nazis. What I think is appropriate is the subject of use of language, sensitivity about perceived attack even when no one really has attacked you, arrogance (Friend 1 dismissing Friend 2 as "ignorant"), comparison of ancient monsters (Alexander) and more modern ones, even the fact of the Soviets and the Chinese fighting against Japan during WW2 (not something often discussed in Europe).
