“Ben-Gurion probably never heard the word “Nakba,” but early on, at the end of the 1950s, Israel’s first prime minister grasped the importance of the historical narrative. Just as Zionism had forged a new narrative for the Jewish people within a few decades, he understood that the other nation that had resided in the country before the advent of Zionism would also strive to formulate a narrative of its own. For the Palestinians, the national narrative grew to revolve around the Nakba, the calamity that befell them following Israel’s establishment in 1948, when about 700,000 Palestinians became refugees.
By the end of the 1950s, Ben-Gurion had reached the conclusion that the events of 1948 would be at the forefront of Israel’s diplomatic struggle, in particular the struggle against the Palestinian national movement. If the Palestinians had been expelled from their land, as they had maintained already in 1948, the international community would view their claim to return to their homeland as justified. However, Ben-Gurion believed, if it turned out that they had left “by choice,” having been persuaded by their leaders that it was best to depart temporarily and return after the Arab victory, the world community would be less supportive of their claim.”
Here is a relatively long but essential read. You may have to register at the Ha’aretz site, but it’s worth it. It tells the story of Ben Gurion’s efforts to spin the exodus of Palestinian refugees by ordering research intended to substantiate the narrative that the flight was voluntary.
