Firstly:
Okay now for the post.
When Palestine is liberated, I think the vast majority of settlers will either be [redacted] or forced out of the region. There is no way that any Arab in the region will accept having a settler in their land, and the settlers know this. The plan will have to be a mass exodus for the west, both for their safety and livelihood (I can see many going into ghoul industries like defense, tech, and police training).
That being said, how would you react if your country decides to accept settlers? Would you support the move? If they were going to live in your community/ neighborhoods how would you feel?
I don't see the purpose of asking this question when Israel is still extant and capable of surviving while Palestine burns. Israel hasn't surrendered because they can do this attrition warfare longer than Gaza can hold out, despite any gains or advantages Ansrallah and Hezbollah have over Israel at the moment. Israel and the US are both willing to escalate in calculated and measured ways.
Considering that Jewish Israelis are 70% of the population, it's likely that they will stay in the long term. Before Oct 7th, there was already a sort of exodus of Israelis to Europe/US because of lack of economic opportunity, high rents, low wages; reasons people leave their country as it is. Israel is not really stable without US support.
