War is a terrible thing,and that's putting it mildly,in comparison to the brutal reality of it. Is it or has it ever been justifiable? I think so,in some cases when righteous people have been forced to fight for their lives by barbarian invaders,but there is no justification for the hostile barbarian invasion, the barbarians aren't rational,and cannot,will not,be reasoned with,so must be utterly defeated and eradicated.Those who are unable or unwilling to accept this universal truth, have been all through history,and still are today, always the first to be the defenseless,slaughtered victims of the savages.
