Whenever I'm around Britons, they're always slagging on the Germans. If there are any French around, they join in. (although maybe only to avoid becoming targets themselves?) When I ask why they won't stop picking on the poor Germans, it becomes very clear that they haven't "moved on". I presume that e.g. Poles or Czechs would agree, but I haven't had the opportunity to find out.
If you get to know e.g. Filipinos or Singaporeans, especially those of a certain age, you'll find they have similar feelings about the Japanese. History has consequences. I fear for my own nationality...
I don’t know which part of my comment you found inaccurate, I’ll be happy to explain further.
