In the first week after the passage of the U.N. partition plan, Arabs
murdered 62 Jews. In the following month, Arabs killed an additional
200. By March 1, 1948, 546 Jews had been murdered and, by Ben-Gurion’s
declaration of independence, the total was over 1,000.[19] Arab
paramilitaries, militias, and terrorists besieged Jerusalem and cut
the Jewish neighborhoods’ water supplies and surrounded Jewish
villages in the Negev. Arab snipers attacked Jews in Haifa and other
mixed villages.[20] A sniper from Beit Dajan shot a 14-year-old girl,
[21] and Arab fighters attacked more than a dozen kibbutzim between
December 1947 and March 1948.[22] Massacres were common: Arab rioters
killed 39 Jews at Haifa’s oil refinery on December 30, 1947, and two
weeks later Arab irregulars killed 35 Jews trying to reach Gush
Etzion. On February 1, 1948, an Arab terrorist blew up The Palestine
Post building and, three weeks later, a terrorist’s bomb killed 44
Jews on Jerusalem’s Ben Yehuda Street. Massacres continued for weeks
both inside Palestine and in the neighboring states.[23] On March 21,
the bodies of 11 missing Jews were found; three had been burned.[24]
Local Arab villagers or Bedouins may have precipitated the autumn 1947
violence,[25] but by spring 1948, Arab volunteers from Iraq and Syria
were increasingly participating.[26] On April 11, 1948, for example,
Egyptian members of the Muslim Brotherhood attacked Kfar Darom near
Gaza City.[27]
Like you say, the proof is in the pudding.
