In Sinclair Lewis's book "It Can't Happen Here," he reflects on the fervor and irrationality that can emerge during times of war. He recalls how the American public went to great lengths to express patriotic sentiments, such as renaming common items like sauerkraut to 'Liberty cabbage' and even suggesting the renaming of German measles. This highlights the absurdity that can arise from nationalistic fervor.

Lewis also criticizes wartime censorship, suggesting that it stifles honest journalism and free speech. He draws parallels between American war-time practices and the repressive tactics seen in Russia, illustrating the dangers of sacrificing democratic principles in favor of collective hysteria. His commentary serves as a warning against the loss of civil liberties during tumultuous times.
