All this regurgitating of modern history and ancient history is just intellectual masturbation.
Who was there first? Who was expelled by who? Who attacked who? None of it matters. What matters is now.
For example, Poland has probably been invaded more than just about any country in history. The people who live there now are a product of millenia of changes.
Today the state of Israel occupies a nation within its borders. There is no point whining about the past. The simple fact is they are not going anywhere - ever!
Instead of living in ghettos waiting to go "home" Palestinians ought move on like countless people before them and either asssimilate into neighbouring arab countries [who, surprise, surprise don't want them] or accept relaity and start building their own country where they are.
The Palestinians have never missed an opportunity to miss an opportunity. They don't seem to wan tpeace. Quite frankly, I am over them. I am surprised Israel shows as much tolerance as they do and don't drive just all of them into the Sinai. They've had over half a century to act like adults and went from the Munich massacre to Yassar Arafat and now to Hamas. They deserve all they get.
