We now have an agreement with Iran to restrain their pursuit of nuclear weapons, but just how good a deal is it? President Obama, congress, presidential contenders, and political commentators are debating that right now. Sojourners offers clear-eyed support for the deal as “better than the alternatives” and clearly better than military strikes which “would be, at best, premature, as well as highly unpredictable and morally irresponsible in creating yet another U.S. war with a Muslim country.”

Even so, Sojourner’s President Jim Wallis has written that he has no doubt that Iran is “an enemy of America, an enemy of Israel, and an enemy of peace.” But as a Christian, he also believes that “you need to find ways to make peace with your enemies.” This deal, for Jim Wallis anyway, seems to be a way to do that. But how do you make peace with a nation that is not just our enemy, but an enemy of peace itself?

Just what is an enemy? We don’t often ask that question because we think the answer is obvious: enemies are bad guys who hate us for no good reason. An enemy is so unlike us that we compare ourselves to them in terms of opposites: rational/ irrational, nonviolent/ violent, law abiding/ criminal, and just/ unjust. We believe that we and our enemy have absolutely nothing in common except perhaps a shared desire to defeat the other.

But I think that way of thinking about enemies is just plain wrong. The cause of the mistake is a basic misunderstanding of human psychology, specifically the psychology of desire. Our enemies are not our opposites; they are the mirror image of our desires. In this way, “an enemy” is not someone separate and distinct from us, rather they are a product of our relationship with them. The best way I know of illustrating this is with a story about desire in my 2-year-old granddaughter, Grace.
