„Why should we add your book to the atomic weapons arrayed against us by our enemies. Publication of your book would help our enemies.“

1950s, Loving Your Enemies (Christmas 1957)
Contesto: Let us move now from the practical how to the theoretical why: Why should we love our enemies? The first reason is fairly obvious. Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that. Hate multiplies hate, violence multiplies violence, and toughness multiplies toughness in a descending spiral of destruction. So when Jesus says "love your enemies," he is setting forth a profound and ultimately inescapable admonition. Have we not come to such an impasse in the modern world that we must love our enemies-or else? The chain reaction of evil-Hate begetting hate, wars producing more wars-must be broken, or we shall be plunged into the dark abyss of annihilation.

1950s, What Desires Are Politically Important? (1950)
Contesto: We love those who hate our enemies, and if we had no enemies there would be very few people whom we should love.
All this, however, is only true so long as we are concerned solely with attitudes towards other human beings. You might regard the soil as your enemy because it yields reluctantly a niggardly subsistence. You might regard Mother Nature in general as your enemy, and envisage human life as a struggle to get the better of Mother Nature. If men viewed life in this way, cooperation of the whole human race would become easy. And men could easily be brought to view life in this way if schools, newspapers, and politicians devoted themselves to this end. But schools are out to teach patriotism; newspapers are out to stir up excitement; and politicians are out to get re-elected. None of the three, therefore, can do anything towards saving the human race from reciprocal suicide.

Often attributed to Stalin, there is not a single source which show that Stalin said this at any given time. There is only one source outside the blogosphere which attributes the quote to Stalin, but does not provide any evidence for the attribution. That source is the book Quotations for Public Speakers : A Historical, Literary, and Political Anthology (2001), p. 121 by the former US senator Robert Torricelli.

"Rectify the Party's Style of Work" (1942)
Originale: (zh-CN) 为什么要有革命党？因为世界上有压迫人民的敌人存在，人民要推翻敌人的压迫，所以要有革命党。就资本主义和帝国主义时代说来，就需要一个如共产党这样的革命党。如果没有共产党这样的革命党，人民要想推翻敌人的压迫，简直是不可能的。我们是共产党，我们要领导人民打倒敌人，我们的队伍就要整齐，我们的步调就要一致，兵要精，武器要好。如果不具备这些条件，那末，敌人就不会被我们打倒。

There are those who would stop at nothing to injure our economy and our defence. The price of liberty is still eternal vigilance. I know what a fine part the trade unionists of this country have played in our recovery effort. When they are asked to take unofficial action, which may hurt this country, let them just consider carefully whether the motives of those who ask them to strike are really concerned with the interests of the workers.
