The fact is Saddam Hussein was sponsoring terrorism in Israel at $25,000 a car and a house a pop thus securing the financial security of suicide bomber's families. It was Israeli intelligence which suggested that Saddam was developing weapons of mass destruction which lead to Gulf War II. Iran is no different to North Korea, Pakistan, India, China, Russia, France or the United Kingdom. Mutually assured destruction will ensure that even if Iran did procure a nuclear device thus achieving parity with Israel it is not an existential threat to the United States. It is only Israel which has stated that Iran achieving nuclear parity with Israel is an existential threat. As a consequence any military action by the United states will be for the benefit of Israel. Nice try though 10 out of 10 for effort. Besides Iraq is predominatly Shia what did you expect would happen when Saddam a sunni was overthrown?
