<P> David Ben - Gurion reorganized Haganah and made conscription obligatory . Every Jewish man and woman in the country had to receive military training . Thanks to funds raised by Golda Meir from sympathisers in the United States, and Stalin's decision to support the Zionist cause, the Jewish representatives of Palestine were able to purchase important arms in Eastern Europe . </P> <P> Ben - Gurion gave Yigael Yadin the responsibility to plan for the announced intervention of the Arab states . The result of his analysis was Plan Dalet, in which Haganah passed from the defensive to the offensive . The plan sought to establish Jewish territorial continuity by conquering mixed zones . Tiberias, Haifa, Safed, Beisan, Jaffa and Acre fell, resulting in the flight of more than 250,000 Palestinian Arabs . The situation pushed the leaders of the neighbouring Arab states to intervene . </P> <P> On 14 May 1948, on the day the last British forces left from Haifa, the Jewish People's Council gathered at the Tel Aviv Museum and proclaimed the establishment of a Jewish state in Eretz Israel, to be known as the State of Israel . </P> <P> Immediately following the declaration of the new state, both superpower leaders, US President Harry S. Truman and Soviet leader Joseph Stalin, recognized the new state . The Arab League members Egypt, Transjordan, Syria, Lebanon and Iraq refused to accept the UN partition plan and proclaimed the right of self - determination for the Arabs across the whole of Palestine . The Arab states marched their forces into what had, until the previous day, been the British Mandate for Palestine, starting the first Arab--Israeli War . The Arab states had heavy military equipment at their disposal and were initially on the offensive (the Jewish forces were not a state before 15 May and could not buy heavy arms). On 29 May 1948, the British initiated United Nations Security Council Resolution 50 declaring an arms embargo on the region . Czechoslovakia violated the resolution, supplying the Jewish state with critical military hardware to match the (mainly British) heavy equipment and planes already owned by the invading Arab states . On 11 June, a month - long UN truce was put into effect . </P>
