The best we can do is seek to transform ourselves and those around us into kinder, gentler versions of ourselves. This is a struggle that never ends and begins anew every time a new child is born. Success is only ever temporary and only ever a mitigation not a total victory. For all that it is an effort worth making but utopian dreams of a New Jerusalem are more of a hindrance than a help along the way. But it's one thing to say war is stupid, another thing is to say it's futile. It’s such a facile, throwaway line. Of course war is terrible, and futility is certainly a frequent aspect. It’s like saying that murder is bad, and claiming some moral superiority because you’ve said it. But irrespective of the claims of pacifists, it takes only one side to start a war. It’s just that a war with only one side is more commonly called a genocide. So rather than take a simplistic, clean view, one that protects your own conscience at the (possible) expense of other people’s lives, why not instead try to understand that war is deeply complex.
