No one was kicked out of Israel when it was declared a country in 1948. The “right of return” is for Arabs who left Israel on their own accord, with the promise that they could return when all the Jews were dead. Israel, of course, recognizes no such right, and well they shouldn’t.
The civil war and resulting UN interference to turn Lebanon into a refugee camp for Pallies, Hezbollah and other imported foreigners transformed Lebanon into what we have today.
Now, the natives are trying to transform it back. A Lebanon for Christians and moderate Muslims is a giant step toward restoring that peace.
