In Martin Gilbert's "Winston S. Churchill: The Prophet of Truth, 1922-1939," the author highlights Churchill's perspective on the Nazi regime. He believed the pervasive persecution carried out by the Nazis illustrated the incompatibility between their ideology and the principles of Parliamentary democracy. Such extreme actions led Churchill to conclude that any hope for meaningful dialogue or reconciliation between the two systems was futile.

Churchill's conviction was rooted in the belief that the fundamental values of Nazism could not coexist with democratic ideals. The systematic oppression and brutality perpetrated by the Nazis served as clear evidence of their totalitarian nature, reinforcing his stance on the necessity of opposing such threats to freedom and democracy.
