13. Why are many Germans both proud and uneasy about their culture

I am German and I can not confirm this claim. But I think the question might be referring to the first and second world war, which were both caused by Germany. Also the history of the Nazis is an issue. Still, people are neither feeling proud nor uneasy about it. That's just what the other countries think. For Germans it's also just history, since (almost) no one who is still alive was involved in any of those events.

Iam pretty sure it is c. 2000 bce
