“On the Jewish High Holy Days, should we be praying mostly for the Jewish people, or for all humankind?”

One of the innovations of the Reform Movement’s new High Holy Day Prayerbook is in the “Kaddish” and in the prayer “Oseh Shalom,” we pray for peace “on us and on all Israel” (al kol Israel), but we add “on all who dwell on earth” (al kol yoshvei teivel).  [Mishkan HaNefefesh, p. 70 and p. 90].
