When war between Israel and Iran seemed imminent, Israeli graphic designer Ronny Edry shared a poster on Facebook of himself and his daughter with a bold message: "Iranians ... we [heart] you." Other Israelis quickly created their own posters with the same message -- and Iranians responded in kind. The simple act of communication inspired surprising Facebook communities like "Israel loves Iran," "Iran loves Israel" and even "Palestine loves Israel."
