The French-born American Trappist monk Thomas Merton (1915–68) wrote in No Man Is an Island (1955,)

Violence rests on the assumption that the enemy and I are entirely different: the enemy is evil and I am good. The enemy must be destroyed but I must be saved. But love sees things differently. It sees that the enemy suffers from the same sorrows and limitations that I do. That we both have the same hopes, the same needs, the same aspiration for peaceful and harmonious life. And that death is the same for both of us. The love may perhaps show me that my brother is not really my enemy and that war is both his enemy and mine. War is our enemy. Then peace becomes possible.
