Sure didn't bother my Dad to drag me by the hair to the recruitment station and off I went. Yes, it's easy for some to just send others off to fight and die while they sit back and reap the profits. War is truly hell!
I should think it would weigh heavily on the mind and heart to send someone off to war. If it truly meant the defense of this country, it might be justifiable, but not easy for a person with principles and integrity.
No parent who loves their children would purposely put their children in danger. But the choice is not ours to make if the child is of an age where he or she chooses to go. And if that is the choice they do make all we can do as a parent is give them our love and support.
