I agree IL, that is just Hitler’s F’d up way of thinking. However, if in 41 he did not have to cover his ass in france (or even the token troops in N Africa, Norway, etc)… would the 6th army have been encircled if a few 100,000 german soldiers were there covering the flanks instead of a bunch of crap Romanian troops? A one on one war with Russia (which is what Hitler wanted) would have probably been a German victory (at that point).
Hitler was a corporal. It shows with how he led his military. His generals were the reason Germany went so far. The tactics are still used, unless you think the “hail marry pass” was not a blitz.
Many times Hitler went too far, but his generals provided him “miracles” which fed his ego that he was a great military comander. Eventualy the miracle well went dry and Germany lost the war.
