That would be an interesting thread. I would ask in that thread if there is going to be one if Germany led in rocket technology for example.
They did to an extent. They certainly did in terms of construction of a large, liquid fueled, ballistic missile (eg., the V-2 / A-4). This was primarily because other nations either terminated such work because of the war (the Soviet Union and UK) or didn't see any value in building such a weapon--at least until nuclear weapons showed up (the US). In 1939, the US and Soviet Union were ahead or on par with the Germans in liquid fuel rocket development. They just didn't see a lot of value in putting a priority on it once the war started.
