Had Zionists intended to expel Palestinians before they came to Palestine ?

Absolutely. It was the plan from the get go. There is no question about it.
ZIONIST ETHNIC CLEANSING QUOTES-In 1895, Theodor Herzl, the founder of Zionism, wrote in his diary:> “We must expropriate gently the private property on the state assigned to us. We shall try to spirit the penniless population across the border by procuring employment for it in the transit countries, while denying it employment in our country. The property owners will come over to our side. Both the process of expropriation and the removal of the poor must be carried out discretely and circumspectly. Let the owners of the immoveable property believe that they are cheating us, selling us things for more than they are worth. But we are not going to sell them anything back.” (America And The Founding Of Israel, p. 49 & Righteous Victims, p. 21-22)For further context:Was there Palestine and Palestinians before 1948?-David Ben Gurion, Israel‘s first prime minister:–On July 12, 1937, Ben-Gurion wrote in his diary explaining the benefits of the compulsory population transfer (which was proposed in British Peel Commission):> “The compulsory transfer of the [Palestinian] Arabs from the valleys of the proposed Jewish state could give us something which we never had, even when we stood on our own during the days of the first and second Temples…We are given an opportunity which we never dared to dream of in our wildest imaginings. This is MORE than a state, government and sovereignty—-this is national consolidation in a free homeland.” (Righteous Victims, p. 142)-Similarly on August 7, 1937 he also stated to the Zionist Assembly during their debate of the Peel Commission:> “. . . In many parts of the country new settlement will not be possible without transferring the [Palestinian] Arab fellahin. . . it is important that this plan comes from the [British Peel] Commission and not from us. . . . Jewish power, which grows steadily, will also increase our possibilities to carry out the transfer on a large scale. You must remember, that this system embodies an important humane and Zionist idea, to transfer parts of a people to their country and to settle empty lands. We believe that this action will also bring us closer to an agreement with the Arabs.” (Righteous Victims,p. 143)-On the same subject, Ben-Gurion wrote in 1937:> “With compulsory transfer we [would] have a vast area [for settlement] …. I support compulsory transfer. I don’t see anything immoral in it.” (Righteous Victims, p. 144)And in 1938, he also wrote:> “With compulsory transfer we [would] have vast areas …. I support compulsory [population] transfer. I do not see anything immoral in it. But compulsory transfer could only be carried out by England …. Had its implementation been dependent merely on our proposal I would have proposed; but this would be dangerous to propose when the British government has disassociated itself from compulsory transfer. …. But this question should not be removed from the agenda because it is central question. There are two issues here : 1) s
