Later I read this post. I was going to make it an update to the one linked above but decided it needs to have its own link here. It has the provocative title On The Virtues of Killing Children. Get past the title, and it's very well thought out. Here's a sample:
"If we did not care if their children died," I add, "there would be no reason to clutter military emplacements with their presence. If it were not that we are horrified by the deaths of children, the enemy's children would be clear of all places of battle -- because they are, except for the fact that we love them, a hindrance."
"It must be," I tell her sadly, "Here: That we pursue war without thought of the children. That we do not turn aside from the death of the innocent, but push on to the conclusion, through all fearful fire. If we do that, the[ir] children will lose their value as hostages, and [our children] as targets: if we love them, we must harden our hearts against their loss. Ours and theirs."
"We can only do," I must warn her, and you. "We can only do, and pray, that when we are done we may be forgiven."
As a commenter to my earlier post mentioned, we undoubtedly killed children freeing the French from the Nazis. Whether or not the French have forgiven us I don't know, but it's not the French from whom we should seek our ultimate forgiveness for such horrible and necessary acts.
