It is noteworthy, and not in a good way, that an essay by Wendell Berry called “Peaceableness Toward Enemies” — written in response to the 1911 Gulf War — is relevant to the divisions that now exist among Americans. Two passages in particular stood out to me. The first:  

Peaceableness toward enemies is an idea that will, of course, continue to be denounced as impractical. It has been too little tried by individuals, much less by nations. It will not readily or easily serve those who are greedy for power. It cannot be effectively used for bad ends. It could not be used as the basis of an empire. It does not afford opportunities for profit. It involves danger to practitioners. It requires sacrifice. And yet it seems to me that it is practical, for it offers the only escape from the logic of retribution. It is the only way by which we can cease to look to war for peace. 

Notice how in all these ways peaceableness escapes the abuses inherent in hatred, which always is used for bad ends, always does offer opportunities for profit, etc. 

The second should be read with the thought that there are non-physical forms of violence: 

Peaceableness is not the amity that exists between people who agree, nor is it the exhaustion or jubilation that follows war. It is not passive. It is the ability to act to resolve conflict without violence. If it is not a practical and a practicable method, it is nothing. As a practicable method, it reduces helplessness in the face of conflict. In the face of conflict, the peaceable person may find several solutions, the violent person only one.

These passages should be read in conjunction with a poem Berry wrote around that time, called “Enemies.”
