Kat, maybe war is used in timelines because it is something more folks can remember or identify with. Matt says it well, if we don't remember the bad times, what do we have to compare the good times too? Let us all work towards the peace that we want for ourselves and for our descendants. In this Christmas season let us all work towards 'Peace on Earth, Good will towards man!' For that matter, why limit it to the season, why can't we all act like it's Christmas year round?
