That's been the talk for decades. The Americans are still talking that talk (and it was always just talk) which is why they're still quite sensitive about egregious settler violence in the West Bank. Israel has moved on now though I think. We're in to a new, more violent, phase.
There is the as you say egregious settler violence from Gush Emunim religious extremists. They are a distraction imo.
The ongoing annexation of West Bank has been going on since 67. First ten years under Labour Zionism.
Unlike what is happening in Gaza now or what happened in 48 what has been happening in West Bank is incremental ethnic cleansing. Using a legal structure set up by the occupying forces ( against all International law on military occupation) for the gradual expulsion of Palestinians to be replaced by Jews.
From the Israeli historian Ilan Pappe book
The Biggest Prison on Earth page 243
The West Bank, 2005–2017 By 2007, 40 per cent of the West Bank was already under direct rule by Israel; or, in other words, annexed, for all intents and purposes, to Israel. Within this 40 per cent Israel solidified its presence with barriers, military bases and closed military areas (cynically, Israel declared them nature reserves).14 This policy focused on Area C of the West Bank and its main purpose was to downsize the Palestinian population there (there were also calls from senior Israeli politicians to annex the area). In 1967 around 300,000 Palestinians lived in Area C; today there are a mere 50,000. The Jewish population has increased from about a thousand in 1967 to more than 400,000 today.
Watching Al Jazeera and now in West Bank IDF are using "security reasons" to take over land.
These are all well tried and tested techniques of Zionism. Use a crisis as an opportunity so to speak. Use legal methods. Inherited from British Mandate years and "interpretation" of Ottoman laws. And of course "security reasons " to take land.
As Pappe rightly says Zionism is land plus demographics.
Their is no such thing as a Zionist state with Palestinians in it on equal basis.
The West Bank after 67 was a problem. So gradual ethnic cleansing plus a so called peace process which would only lead to some form of self government in specific small areas for Palestinians was to Pappe the "Open Prison" model.
With good behaviour Palestinians would be allowed to run things like schools etc.
This is what the moderate Zionists and the Labour party here as well as possibly the Tories and Biden see as a resolution to the conflict.
The Palestinians have not behaved in Gaza so in this case its being used as opportunity to remove them for good.
Israel has tried to get Gaza and Sinai before. Under David Ben Gurion. Not always successfully. Getting land has always been something that has pushed Zionism. I think it is perhaps a mistake to focus to much on the present government and Netanyahu.
The history of Israel encompasses clearly violent phases ( Nakba) with more gradual violent phases ( structural violence of occupation)
