Let's take a look at that and see where Americas past meddling has gotten us. Since 1979 when Iranian Revolution took place where the Ayatollah Ruhollah Khomeini became Supreme Leader and made Iran an Islamic Republic the American Govt is on its feet to crush the Iranian system and for that they have come out with various ideas from imposing sanctions to wars and debate on Iran's Neuclear program. One of the Example is of serious meddling by the United States is the Iran-Iraq war which lasted from 1980-1988. In 1983, the Reagan Administration provided chemical and biological weapons to Saddam Hussein, leader of Iraq to assist in their fight against Iran. As we all know, Hussein would later invade Kuwait in 1990 leading to the First Gulf War with President George HW Bush and after 9/11, the invasion of Iraq by his son, President George W. Bush becoming the Iraq War (or the Second Gulf War) which continues to this day. Then in the past recent years the American govt tried its level best to bring Iran to its knees on their Neuclear program and the superb administraion, boldness and attitude towards a Zionist illegal state Israel and the double policies of the USA by the President of Iran Ahmedi Nejad. Somehow all the efforts of USa and Israel went in vain and Ahmedi Nejad won the elections again, so the america have come up with a very old but indeed a very strong formula of the British Empire "DIVIDE AND RULE". America is definitely playing dirty politics in Iran and some how they are succeding this time.
