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?
That depends on how the downfall of Zionism is going to play out. If they are just mad about no longer being the master race they're not refugees deserving of special protection, just sore losers. If, on the other hand, retaliatory violence erupts and Palestine tries to expel Jewish residents then many of them can possibly be considered to be refugees.
