Double standard: Iran has said that the double standard applied to Israel is unjust and disturbing given its possession of nuclear weapons, its non-adherence to the NPT, and its treatment of the Palestinians over many years. Israel has unofficially stated it needs to have nuclear weapons to assure its survival in a predominantly hostile Middle East environment, since its independence in 1948 and following the Holocaust. Iran has responded that the Middle East should not bear responsibility for crimes against humanity and atrocities committed by the Nazis during World War II against the Jews in Europe.[15]
