war means people kill people. the decider decided to show the world that he is the boss in charge of deciding & send human beings into a war where they see the constant mayhem of a war with no rules, except the rules that they are supposed to be following.
well, gee, wasn't this good ol us of a founded on the murdering of people who did not have guns, slaughtering people in their homes as they slept, giving out blankets with the smallpox disease to cold people, forcing people at gunpoint to march to horrible places where they could no longer live as they had? etc, etc.
if the deciders of this world would instead be leaders and lead by an example of honor and peace, perhaps we would be led to peace.
