Is that because you believe he interfered with strategic bomber development, Stuart?
James Corum in his The Luftwaffe: Creating the Operational Air War, 1918-1940 (1997) demolished the myth that the Germans dismissed the potential of strategic bombing, had a place in its doctrine for the same, but building the force was a different matter.
Yeah, its one of those wonderfully misinterpreted things that gets twisted on a daily basis by the alt-history fantasy crowd. Depending on the way they decide to set their sails on any given day it either means:
1. The Germans were stoopid because they couldn't do strategic bomming or
2. The Germans would have done the bestest strategic boming ever if they just built the Ju-STRATCOM and nobudy could have stopped them.
The most amusing of that crowd are those that end up arguing both of the above simultaneously.
They could certainly do strategic bombing, walking around Coventry as a child successfully impressed that on me.
Did they lack the tools to do it effectively? Well yes. An RAF 4 engine bomber raid of 500 aircraft had significantly more destructive effects than a Luftwaffe one, which was primarily made up of tactical bombers till the end. And right there is where they failed. They had the doctrine just fine, they didnt have the airframes to carry the tonnage to make it work.
They also didnt build enough of them to keep going. A loss rate of 2.8 percent would have decimated the Luftwaffe in short order. Bomber command lost the equivalent of its entire front line strength on the Battle of Berlin, and kept going. It lost a lot of skilled personnel, but it kept going.
