Orwell's construction of Big Brother as a form of government in which the centralized executive proceeds unchecked and unlimited closely parallels Nazism. For Orwell, there is a danger in an absolute authority in which there is little check or limitation of power. Orwell understood Nazism to pose the same kind of threat to its people as the government in 1984. The outgrowth of the Holocaust and the dangers of silencing voices becomes the overall message of a government in which there is no institutional check on its power and little ability for individual citizens to recall its government. At the same time, Orwell's novel depicts the underlying dangers of "groupthink." When all people are conditioned to think the same and not diverge in the variance of thought, Orwell sees danger. It was certainly the case of Nazi Germany. Few, if any, understood the powerful implications of speaking out, operating as a voice of dissent in a setting that preached groupthink. Orwell recognizes this danger in his novel, one that springs out of what was seen in the social rise and conformity in the groupthink of Nazism. The lack of free will and of individual freedom to serve as a check against the political machinery of a government in which the central authority has grown out of control is a political reflection of Nazi Germany. The rise of individual compliance with groupthink and the lack of individual voice of dissent becomes its social reflection.
