Love Your Enemies

What would "war" look like if we followed the words of Jesus? Here's the text of a speech given by Father George Zabelka, a chaplain at the time of the Hiroshima and Nagasaki bombings:

So the world is watching today. Ethical hairsplitting over the morality of various types of instruments and structures of mass slaughter is not what the world needs from the church, although it is what the world has come to expect from the followers of Christ. What the world needs is a grouping of Christians that will stand up and pay up with Jesus Christ. What the world needs is Christians who, in language that the simplest soul could understand, will proclaim: the follower of Christ cannot participate in mass slaughter. He or she must love as Christ loved, live as Christ lived and, if necessary, die as Christ died, loving ones enemies.

I've often wondered what it would mean to "love your enemies" in situations of war (Matthew 5:43-45), to remember that love casts out fear (1 John 4:17-19), to see how terror might be better confronted with the grace and mercy of Jesus in some creative and redemptive way. I know countries fight wars, and soldiers live and die for the cause - but is there another way, perhaps no less dangerous, but ultimately right in really changing hearts and lives?
