Those left behind have no place in history but within a statistical generality or as a symbol or example of what is totally lost. Their fate is clear: to recount and testify to what has happened. They carry with themselves such inescapable fate and no matter how hardly they try to explain or change it, future will not listen to them.
I would prefer to concentrate my attempts on recording the being-left-behind rather than trying to deny or change it.
History cannot be recycled: as for an abandoned empty shell of a bullet, the broken glass of a window, severed ropes and stones taken from the riverbed to become the means of torture.
From whatever angle you approach it, there is no way to the future for the events of the sixth decade and their left-behinds.
