Overload , you are starting to confuse yourself,
We are talking about expulsions, you are talking about emmigration. Carrots on sticks and a happy family waiting for you at the other end. You are talking about voluntary transfers to voluntarily recipient countries. You are talking a fantasy of a couple of million people waking up in the morning and thinking "Ahh Sure I think Ill be off, c'mon Kids , were off to Syria to live with Uncle Ahmed." in their Hundreds of thousands....Rubbish, Rubbish, Rubbish.
You will not get a mass voluntarily exodus of Indigenous Arabs either from, Israel of the Occupied territories. No!
The option is to force those who wont go. This is expulsion and is a violation of Human Rights.
The percentages you quote for encouraging Arabs to leave Israel 40 /42 % , very close and that is assuming it is voluntary through encouragement. Not going to happen , so your percentages are meaningless.
How do you propose to get a mass movement of Arabs voluntarily: explain please or forget it.
