A letter addressed to Israeli Prime Minister Menachem Begin, dated 7 March 1978, and authored by 348 reserve officers and NCOs in the Israel Defense Forces. The letter called on Begin to prefer peace negotiations with a view towards ending the Arab-Israeli conflict to a policy promoting settlements beyond the Green Line and the continued control over "around one million Arabs", jeopardizing Israel's Jewish and democratic character. The letter, and the support given to it among some Israelis, is considered to have led to the establishment of the Israeli left-wing NGO Peace Now.
