Has little to do with Christ and his whereabouts, my friend.
It's a simple question: how far is a civilized society willing to go in terms of destruction? In recent years, the question has been answered fairly certanly: we now use GPS, laser and computer-guided munitions. We take pains to NOT hit civilian targets.
Some will pooh-pooh this sense of care about what we hiot as mere public relations. I'd like to think that having witnessed firsthand the damage that was done to civil society by indiscriminate bombing, that westerners have taken the moral aspects of war into account in a way their forebears certainly did not.
