If you're suggesting that a peoples' right to live in their homeland is forfeited as a result of immigration, terrorism or ethnic cleansing, that would be bad news for Palestinians. Gaza and WB Area A are Jew-free zones, and there were around 30k rocket attacks from Gaza alone.
The explicit goal of Hamas is the ethnic cleansing of Israel of all Jews.
