On this subject Ive just finished the Palestinian historian book on the debates within Zionism about removal of Palestinian Arabs to make a Jewish State.
In this meticulous work, based almost entirely on Hebrew archival material, Nur Masalha examines the Zionist concept of "transfer," or the expulsion of the Palestinian population to neighboring Arab lands. Masalha establishes the extent to which "transfer" was embraced by the highest levels of...

This was always part of Zionism from the days of Herzl.
The books goes into detail into the discussions in Zionism about how to remove the non Jewish population from what they saw as the legitimate Jewish Homeland.
And this was not the right wing. The mainstream of Zionism in 1930s was led by David Ben Gurion and other Labour Zionists.
Who wanted a socialist Israel for Jews only.
The problem was how to get to this ideal.
Population transfer with aid of the Imperial authorities ( Britain) or support of US . " Population transfer" was seen as the moral way to do this. With land being set aside in other parts of middle east. The line the mainstream Zionists took was that Arabs had a lot of land and Palestinian Arabs could be rehoused elsewhere.
They took the population transfers between Greece and the new Turkish state as example. Also the possible population transfers post WW2 ( ie Germans being made to leave parts of the new Poland etc)
"population transfer" is discussed as the normal way of doing things. The moral side was plans to pay Palestinians to leave. Give them new homes to go to. The problem some Zionists brought up in 1930s was what if some refused to go. The issue of compulsion was envisaged as carrot and stick. Any new Israel state would make it difficult for non Jewish Arabs to remain. So in end they would go.
The problem was whether they would go willingly. And how to make them go.
Various tentative plans were adopted and politicians/ officials in UK and US were lobbied.
David Ben Gurion and others realised this was sensitive topic so whilst it was no secret decided tactful approach was required.
They thought there vision of a Greater Israel could be obtained through support of the great powers.
David Ben Gurion saw the initial borders of Israel as just the start. They always had their eyes on a Greater Israel. West Bank.
The point is Netanyahu is in long line of Zionists of left and right who have pursued this dream.
It always was inherent in Zionism from its early days.
Netanyahu is not some kind of aberration.
