1. It is not necessary to forcibly transfer anyone. Most Arabs in Yehuda v’ Shomron and 80% in Gaza have admitted that they would leave if they could. Many more probably would but won’t admit it. An international resettlement fund could be set up to pay them to relocate to countries that need immigrants with money (Germany, for example, still needs 800,000 workers). Those Arabs who hold Israeli citizenship state privately that they are not crazy enough to prefer to live in an Arab state. Even in public they scream whenever Lieberman talks about giving the PA the Triangle in exchange for settlement blocs.
2. What about our Ever haYarden?
3. Akuperma, you are forgetting the successful double transfer between Greece and Turkey following the Greco-Turkish War following WW1. There are approximately 1 million Jews in Europe and 1.5 million in the PA (their statistics have been shown to be greatly exaggerated). That would be a fair exchange.
