This business about knowing who to trust and who to appoint is key in being a great politician. That’s why Caesar Augustus, once Octavianus, is probably the greatest politician of all times. He surrounded himself with just the right people, including Agrippa. That’s why Robert Graves’s novel I Claudius was just satire and not reality. The Livia in his novel was really Augustus. He was that shrewd.
Hitler was no Augustus. He appointed all the wrong people to powerful positions and caused his own downfall.
