Oskar Wilhelm Robert Paul Ludwig von Beneckendorff und von Hindenburg (31 January 1883 – 12 February 1960) was a German "Generalleutnant". The son and aide-de-camp to Field Marshal and Reich President Paul von Hindenburg had considerable influence on the appointment of Adolf Hitler as German chancellor in January 1933.
Paul von Hindenburg got Hitler appointed as German chancellor.
The article says that he had considerable influence in his appointment, so without it he very well may not have been appointed. One can not be sure. I think the system probably doesn't have the capacity for hypotheticals.
