History books have had different assessments on the role of Arab countries toward the Zionist Movement's control of Palestine and declaring establishment of Israel in 1949. This paper suggests that Iraq’s position was against the control of the Zionist Movement on Palestine. The three-chapter paper has adopted the historical approach to prove the validity of this hypothesis: Chapter 1 addresses the conditions of Palestine under the British Mandate (1917-1947); Chapter 2 deals with the official and popular Iraqi position toward the Jewish expansion in Palestine during the British Mandate; and Chapter 3 is devoted to discussing Iraq's contributions to the Arab-Israeli wars. The paper concludes that Iraq has taken a supportive stand to the Palestinian rights; but the Iraqi army's contribution to Arab-Israeli wars was limited because of the Arab and Iraqi political decisions, which weakened the important Iraqi role in the Arab-Israeli 1948 and 1967 wars.
