Well unfortunately he's made it necessary to do so. I can like this demo in the same way I can like the V2 rocket as a pioneering achievement in rocketry. There's a very big elephant in the room.
The V2 as a military weapon was a complete failure (due to inaccurate guidance). It also consumed so much of the Reich's resources that it materially shortened the war.
