After doing extensive research on the German intelligence and security agencies like the RHSA, Abwehr and Sicherheitsdienst (SD), I concluded that too much competition between the branches led to a less than effective counter to MI6 or later the OSS. In 1944, after repeated failures and a lack of trust between himself and the Abwehr, Hitler dissolved the agency, denying the Wehrmacht of their own intelligence department--handing over control to the SD. Its common knowledge that Canaris, chief of the Abwehr was less than an enthusiastic party member--even so much as to be labeled an anti-NAZI. And its widely believed, though not proven, that he sabotaged the German intelligence efforts by leaking information. My question is: what if the Abwehr was dismantled earlier in the war, maybe 1940? It could be due to scandal, treachery--you name it, so long as Hitler sees the Abwehr as a threat to the war effort and relinquishes control to Himmler's SD. What effect would this have on the outcome of the war?
