Between 1932 and 1948, Yosef Weitz was the director of the Jewish National Fund's Land Settlement Department. He wrote in his diary:
On 1941, June 22:
"The land of Israel is not small at all, if only the [Palestinian] Arabs will be removed, and if its frontiers would be enlarged a little; to the north all the way to Litani [River in Lebanon], and to the east including the Golan Heights […] while the Arabs be transferred to northern Syria and Iraq […] From now on we must work out a secret plan based on the removal of the Arabs from here [and] to include it into American political circles."
On 1941, June 26:
"Through out the journey my reflections were focused on [the plan] of evacuating the country for us [the settlers]. Only through population transfer will redemption come […] There is no room for us with our neighbours […] They [the natives] are too many and too much rooted [in the country]. The only way is to cut and eradicate them from the roots. […] People and money will be transferred there. We will set up an apparatus from the Yishuv manned by distinguished experts and these will supervise the [Palestinian] Arab transfer and resettlement and a second apparatus will receive the [Jewish] redeemers and plant them in the land."
On 1948, April 28:
"Khayriyah and Saqiyah [two Palestinian Arab villages in the coastal plain] have also been cleared out. My plan is getting implemented."
In 1949:
"[During the British Mandate period, the JNF had purchased land] crumb by crumb. But now a great change has taken place before our eyes. The spirit of Israel, in a giant thrust, has burst through the obstacles, and has conquered the keys to the land, and the road to fulfillment has been freed from its bonds and its guardians-enemies [referring to the natives]. Now, only now, the hour has come for planning considered [regional] plans […] The abandoned lands will never return to their absentee [Palestinian Arab] owners."
