“I threw families onto the street in Iraq, only to come home and find families thrown onto the street in this country, in this tragic and unnecessary foreclosure crisis. We need to wake up and realize that our real enemies are not in some distant land. They're not people whose names we don't know and cultures we don't understand. The enemy is people we know very well and people we can identify. The enemy is a system that wages war when it's profitable. The enemy is CEOs who lay us off our jobs when it's profitable. It's the insurance companies who deny us health care when it's profitable. It's the banks who take away our homes when it's profitable. Our enemies are not five thousand miles away. They are right here at home.”

1950s, What Desires Are Politically Important? (1950)
Context: 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.

"Rectify the Party's Style of Work" (1942)
Original: (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。
