Did the Deutsche Museum with some visiting family this weekend, they seem to keep things very neutral with no reference to the political enviroment. What struck me was the super intricate detail with which everything is explained, for example they show the development of the rocket technology leading upto the V2, then how the V2 rocket itself was built with various alloys and then how they solved the navigation element etc etc. So you can walk past and say 'oh look the V2' or delve deep into the topic.
