Holocaust Reflection(?)

Human life is a precious resource for anyone to have and an absolute necessity on any sort of scale. What could give one faction the right to start committing genocide on another simply because they want someone to blame? Taking the life of another being is not a choice for someone to make, no matter who or what they are, but they do it anyway. Not just the Holocaust was completely trivial, but the entire war was completely trivial. Germany was already going through a hard time, so what made them think that hysteria and hype coming from an unstable man would give them the strength to overrule the world? The same goes for the Japanese; why attack your former source of resources when you are already fighting on another front and your resource provider is a powerful country? It can just go to show how much desperation in a country can overtake the populace and force them to make radical decisions.Sure, both of those countries knew what they were trying to do and believed they could do it, but they were ultimately fighting a losing war regardless of how fearsome and relentless their military was. When the single most powerful country in the world is fighting against you with allies backing them up, it will more than likely end up becoming a losing war. Why throw the lives of your people away like that; why risk facing complete and total loss for something that will work itself out?
