Robin has a fabulous post on peace and what we must do to achieve it. Go read it.
Personally, I've never bought the idea of a Moshiach who will come and rescue us. I tend to believe the idea of Tikkun Olam. I do believe in Moshaich, but I believe he/she will come when we work together to repair the world. He/she will work WITH us, not in spite of us. And no, I'm not in any way insisting that Barack Obama is a messiah. @@
