It’s probably true that now that women can qualify to fight in all combat situations that there isn’t much of an argument against requiring them to register for the draft. If that makes mothers and fathers all across this land a little less likely to casually advocate the use of military force anywhere in the world where someone makes us remotely uncomfortable, it’s probably a good thing.

There are certainly arguments against having women in combat. We’ve all heard them. Maybe you are convinced by them. However, the decision has been made. It’s a little late to be debating the topic as if the policy was still under discussion.

Of course, the military can make mistakes, but they wouldn’t have signed off on this policy change if they agreed with Kathleen Parker that it will cause a massive erosion in unit cohesion. I think she ought to be a little more circumspect in relying on her intuition as a better guide than all the studies that have been conducted by the Pentagon.

What I find most objectionable, however, isn’t that Parker disagrees with the Pentagon. What I find appalling is her cowardice.

For now, as America is focused on the Islamic State and the presidential election, women in combat will just happen one day sometime in the not-distant future. Eventually, we’ll avert our eyes from footage of a young woman’s tortured body — someone’s wife, mother, daughter, sister or lover — as she is crucified, burned or beheaded in the name of God knows what.

That will be a day no civilized nation should have invited upon itself.

It’s a stretch to talk about a “civilized nation” when husbands, fathers, sons, and brothers are being crucified, burned, and beheaded. But if the enemy is worth fighting and that’s what they do to those they capture, then that’s the risk we ask our soldiers to take. The hope is that our soldiers are more civilized than their opponents.

If you feel the need to avert your eyes when one of our own is tortured and dismembered, by all means, avert your eyes. No one wants to watch such things. But I don’t see why they are tolerable when they happen to our young men but not our young women.

What makes war justifiable, if anything, is the barbarousness of the enemy, not their adherence to human rights. If they need killing, then we have to accept that we’ll suffer casualties and horrors of all types.

And, again, if the prospect of having some of our daughters suffer the same fate as our sons makes people less likely to risk the lives and well-being of either, I count that as a good thing.

Squeamishness is a useless personality trait in war. Moral scruple is important. Cowardice is not.
