Those are the descendants of those displaced in 1948.
They should not still be refugees.
Two million German speakers were displaced in 1945.
All settled.
More Jews than Arabs were displaced in 1948.
All settled.
There is no ethnic cleansing of Arabs from Israel.
None are leaving Israel for a better life in Arab countries.
You made that up Jim.

Why do you need to do that if Israel is so evil?

Why does no decent government accuse Israel of massacres, war crimes or ethnic cleansing?
Because it is all bollocks made up by people you hate Israel.
Like you Jim.
