The following link belongs to a jewish association in U.S. dedicated to bring peace on Palestine-Israeli conflict. http://jewishvoiceforpeace.org/
What they declare in their statement of mission is that they seek for peace based U.S. foreign policy. From this perspective, they are taking their positions against to a policy which is lasting for last two centuries. I do call everyone to help and perpetuate this sort of associations by joining them and contributing them. Even sharing these kind of things in individual network helps little bit to reach out to the possible volunteers.
