In England and the United States, in Denmark, Norway, and Sweden, in Switzerland and Canada, democracy is today sounder than ever before. It has defended itself with courage and energy against the assaults of foreign dictatorship, and has not yielded to dictatorship at home. But if war continues to absorb and dominate it, or if the itch to rule the world requires a large military establishment and appropriation, the freedoms of democracy may one by one succumb to the discipline of arms and strife. If race or class war divides us into hostile camps, changing political argument into blind hate, one side or the other may overturn the hustings with the rule of the sword. If our economy of freedom fails to distribute wealth as ably as it has created it, the road to dictatorship will be open to any man who can persuasively promise security to all; and a martial government, under whatever charming phrases, will engulf the democratic world.
—Will Durant, The Lessons of History (1968)
