Palestinian refugees, 1948
To the question ”Don’t Israelis or Jews have the right for a national homeland, a safe homeland?”, Gilad Atzmon answers:
“Strictly speaking the answer is NO. If the Jews ever had a right for a national home, they lost this right a long time ago. As we know Zionism celebrated the Jewish national revival at the expense of the Palestinian people.
Would you allow a bunch of Italian lunatics to invade your home in Athens just because they are convinced that your dwelling was once part of the Roman Empire? They could claim that your home was a property of their Roman forefathers. Clearly, Italians wouldn’t get away with it, but Zionists did, at least for a while.
There is no right for a racist state that celebrates its tribal symptoms at the expense of others.”

(*) The Nakba (Catastrophe in Arabic) has never ceased. This is the story of the deliberate destruction of Palestine. Annihilation accompanied by massacres and programmed expulsions against its Arab residents. The Nakba is an ongoing process, not the past.
