when apartheid south africa ended, the people remained. populations were not mass deported as you're suggesting must happen to end occupation - simply ahistorical. why is that more farfetched to you than mass deportations (to, as you say, where?)
btw, i used "they" to refer to the same "they" that you wrote. don't insinuate anything with scare quotes.
I yet to see "let's end the occupation" call that resulted in a less naive conversation.
What you propose is not a plan or a decent answer to "how to end occupation".
