Michael Espersen: Background on the Palestine War
On the Zionist side, the Israelis had one of the most formidable armies in the Middle East, due to mass immigration, superior weapons, and support from outside sources. On the Palestinian side, the Arab armies were disorganized, led by poor leaders, and had inferior equipment from WW1 and before. The great majority of the fighting, perhaps as much as 80% of the battles, took place on Arab-occupied land, with much of the war consisting of Israeli troops invading Arab towns and occupying them for Israel.
According to Israeli historian Benny Morris, the 1948 war consisted of two phases: November 1947 to May 1948, and May 1948 until the February 1949 armistice agreements. By the end of the war in 1949, over 700,000 Arabs had fled or been forced to leave their homes by the Israeli army, and Israel had occupied almost 80% of what was originally Palestine. Israel never allowed any of the refugees to return, and the Palestinian refugee problem continues even until today, with the great mass of the Palestinian refugees clinging to the hope that one day they and their descendants will return to the land of their ancestors.
