In 1947 the Palestinian movement started an unprovoked war against the Yishuv, the Jewish population in the land of Israel. The explicit goal was to displace the Jewish population and prevent further Jewish refugees from arriving. It is entirely unclear to where the displaced Jewish population would be deported and the likely outcome had the Jews lost the war would have been a second Holocaust. Palestinian forces systematically shut off roads to Jewish villages in an attempt to prevention delivery of essential civilian goods to the Jewish community.
The Haganah (Hebrew meaning “Defense”) Jewish military forces had no choice but to displace those who wanted to displace the indigenous Jewish people. The alternative was allowing genocide. Palestinian villages that were friendly or who had declared neutrality were generally not displaced.
Those Anti-Zionists who shed crocodile tear about the Palestinian Nakba ignore that the Palestinian movement ever since the inception of the Zionist return to the land of Israel in the 19th century have sought a Jewish Nakba. Even today does the Palestinian Authority officially seek a Jewish Nakba of 600 000 indigenous Jews from Judea, Samaria and East Jerusalem. 700 000 Palestinians were displaced in Israel’s 1947-49 War of Indepence which included all neighboring states invading the nascent Jewish state in 1948. 850 000 Jews were displaced from Muslim countries from 1948 to the 1970s. Judea, Samaria and East Jerusalem were entirely ethnically cleansed from Jews in 1948.
Without claiming this as an official diplomatic position does the Palestinian Authority in its domestic rhetoric as expressed in regime schools and regime media seek a larger Jewish Nakba of 7 million Israeli Jews to be displaced from their homes and deported to other countries. Considering the depth of the hatred among Palestinians against Jews (now and in 1947) can there be little doubt that such displacement would lead to anything else than genocide.
