It is a popular policy amongst Israelis as they fear for their future security. In addition a lot of Palestinians want to leave the territory and I was listening to a young Palestinian woman openly admit she sees no hope for her children in wasteland and therefore would readily accept moving to another country to allow her family a prosperous healthy life. I think this is a view that is under reported and the media are actively seeking out Palestinians who wish to remain in Gaza to interview.
When Hamas start criticising a policy as being racist and against human rights we really have to look at our selves if we take statements from the instigators of October 7th seriously. The excursion of Palestinians from Gaza would allow the backing of Hnas and other ideologically hateful groups to be dissipated and a threat removed at least partially from Israel.
We also have to consider the success of migration and to look at migration purely with the lens of ethnic cleansing maybe skewed. There are many people from the middle East that wish to live in Europe as evidenced by immigration being a bit topic politically so to say moving from a middle Eastern elsewhere amounts to a hideous punishment is simply not the case.
No one as far as I can see has put down a hopeful vision for Gaza except for being an impoverished sub state reliant on global charity for its existnce. Surely long term this can only lead to resentment amongst people that a leads to the political climate that views jihad and terrorism as an outlet for suffering. It also doesn't help that Hamas and presumably a majority of the Palestinian people won't relinquish maximalist goals in terms of reverting Israel to Palesrinain rule and this view can never sit with the idea of a long lasting peace.
It therefore seems pragmatic to look at emigration as a solution to the Gaza conflict as there are some for all people. The Israelis gain security, the Palestinians have hope for their families with less fear of poverty and war. Hamas do not have a geographical base and the hate filled ideology will suffer.
I don't think Trump articulated this well but some of his policy deserves at least a hearong.
