No argument. if the option is between near certain death due to bombardment or starvation and living in Brazil or ireland. I imagine most will take that choice, if of course it was given.
Bombarding people or starving people to force them to leave is forced displacement, and so is a crime against humanity. The solution here is for the party committing the crimes to stop, not for the victims to give their land to the criminal party.
Nor is available power and leverage being brought to bear on stopping them. Any honest attempt at helping innocents being traumatized would start there.
Then yes, facilitating voluntary movement after that would help, without also blatantly facilitating those who want to drive them out.
