Less effective Deutsche Wochenschau = shorter WW2?
Hitler made no public speeches after 1943. It is no exaggeration to say that it was Goebbel's speeches and the work of his Propaganda Ministry that stiffened German resolve immeasurably in the face of retreats on all fronts 1943-45. So much stiffening, that in OTL the Nazis literally had to be fought all the way to the Fuhrerbunker.
The greatest of his the Reichsministerium fur Volksaufklahrung und Propaganda's tools was the Deutsche Wochenschau. As can be seen from its excellent footage, fanatically patriotic baritone commentary, and inspiring music eg when shown the footage of the Battles of Arnhem & the Bulge, even at that stage of the war, the German populace was convinced that they were literally winning.
The question is: WI the PK crews were less effective, dedicated & inspired, like the pathetic British Pathe News, so that there's less resolve to fight ie with a less efective Goebbels & his minions, would the war have been shorter?
