I have a Jewish friend who grew up in New York City and lived in a kibbutz in Israel for a time. She is very aware of the politics of the Mideast, and has compassion for all those who are suffering there.
She organized a Palestinian-Jewish discussion group here in the US, which started out with people saying they could not agree on anything at all, yet she persisted and when they agreed on where and when to meet the second time, she pointed out that they had made a joint decision! Small steps are very important in such things.
She has been studying Arabic and plans to return to Israel to organize a joint project for Israeli and Palestinian children ... a play (which I believe will be a musical).
I have heard a saying, "no need to shovel out the darkness, just turn on the light!" or "it is better to light a candle than to curse the darkness". Sometimes we all tend to mourn for the terrible things that happen between people when they see their differences and hate one another, and kill one another. Rather than protesting about all the apparent injustice in the world, this friend decided to do something to be part of the solution.
