In its defence, Israel has argued that it does not have the intent to systematically destroy the Palestinian people and that its war is against Hamas, a group it and several countries, such as the United States, have designed as a terrorist organisation. It has also argued that, in fact, Israelis are the target of genocidal campaigns of Hamas and allied groups like Hezbollah, both of whom are supported by Iran. To be sure, both Hamas and Hezbollah are committed to the destruction of Israel and Israel's archenemy Iran has since the Islamic Revolution of 1979 maintained it is a "cancerous tumour in the West Asian region that has to be removed and eradicated".
