there is no obvious division between east and west. the neighborhoods obama has been complaining about (gilo, ramat shlomo etc) are not in east Jerusalem as obama says, but in northwest and southwest jerusalem. the eastern portion, where arabs live, is the holy basin (Old City, Kotle, mount of olives etc). If Israel gives up the holy basin, we will have lost our soul. if we give up the south and north and east, we will give up security and we will have no place to put the jews of jerusalem.
