You have a good point (about people lining their children up in front of tanks). I don't see how the parents sent their children out to carry grenades during Viet Nam or how the people sent out their little ones during the Crusades, for that matter. I keep hoping we have evolved enough to fight our own battles and leave the children out of it. This also applies to parents in a bad marriage who are torturing their kids by the way they behave. Obviously, it's not as bad as putting them in front of tanks,but it's the same kind of disregard for those who are supposed to be most important to you.
re: "people sent out their little ones during the Crusades."
I'm not so sure about that one! I think you are referring to the "Children's Crusade", in 1212. The parents did NOT send their children away!
Instead, they were convinced by a peasant boy named Stephen to leave. It is believed by many that from this actual historical event, we have the medieval tale: "The Pied Piper of Hamlin".

The "Crusade" was preached in France by a peasant boy named Stephen from a village near Vendome. In Germany, a boy named Nicholas from Cologne started the movement. The sorry business was summarized by a chronicler in these terms:
In this year occurred an outstanding thing and one much to be marveled at, for it is unheard of throughout the ages. About the time of Easter and Pentecost,4 without anyone having preached or called for it and prompted by I know not what spirit, many thousands of boys, ranging in age from six years to full maturity, left the plows or carts which they were driving, the flocks which they were pasturing, and anything else which they were doing. This they did despite the wishes of their parents, relatives, and friends who sought to make them draw back. Suddenly one ran after another to take the cross. Thus, by groups of twenty, or fifty, or a hundred, they put up banners and began to journey to Jerusalem. They were asked by many people on whose advice or at whose urging they had set out upon this path. They were asked especially since only a few years ago many kings, a great many dukes, and innumerable people in powerful companies had gone there and had returned with the business unfinished. The present groups, morever, were stfll of tender years and were neither strong enough nor powerful enough to do anything. Everyone, therefore, accounted them foolish and imprudent for trying to do this. They briefly replied that they were equal to the Divine will in this matter and that, whatever God might wish to do with them, they would accept it willingly and with humble spirit. They thus made some little progress on their journey. Some were turned back at Metz, others at Piacenza, and others even at Rome. Still others got to Marseilles, but whether they crossed to the Holy Land or what their end was is uncertain. One thing is sure: that of the many thousands who rose up, only very few returned.
