I guess that war, as well as peace, is in our human nature. Here is an interesting quote:

"Peace is not an absence of war, it is a virtue, a state of mind, a disposition for benevolence, confidence, justice."
-Baruch Spinoza

We can find a state of peace in every small gesture of kindness and justice, especially in a world riddled with war. It is so true that only in the stark contrast of evil can we appreciate the good. And a daring act of goodness can be witnessed and then told as a story again and again to keep us going despite the traumatic events of the day. Go see the movies "Monsoon Wedding" or "Kissing Jessica Stein" - in those stories, the brave loving parents emerge as the heroes of the tale.
