A much better result would have been if the US had not propped up Saddam during the Iran-Iraq war in the first place. Or, alternatively, if the US had not given Saddam the green light to butcher the shia and the Kurds even after Desert Storm, when they rose up in rebellion and when the US allowed Iraq to use helicopter gunships to mow them down. Except for Western Iraq, the rest of Iraq (southern Iraq, Baghdad, the Kurdish region) has historically been part of Iran's sphere. Iraq itself was ruled by Iran from the time of the Achaemenids (4th century BC) to Sassanids (6th century AD). Later, when the capital of the Islamic caliphate moved to Baghdad (on the site of the ancient Iranian city of Cteisphone), it marked the rise of Iranian political influences over the Islamic caliphate, best exemplified by the fact that the Caliph Mansour was born to a Persian mother and filled his court with Persian ministers. Many historians call the Abbasid caliphate an "Iranian empire in Islamic garb". Even the Arab essayist of the time, Al Jihaz, called the Abassid caliphate "Khorasanian and Persian", distinguishing it from the Arab Ummayad Caliphate that preceded it. (The Ummayads were overthrown by a Persian army raised by a Persian Abu Moslem from Khorasan in northeastern Iran). Iraq was also the battleground state between Iran and the Ottoman empire throughout the 16th to 19th centuries. Militarily, the Ottomans had the upperhand for most of that period, although there were stretches were Iran enjoyed predominance in Iraq, but spiritually, many historians regarded the triumph of "shi'ism" in Iraq as a spiritual victory for Iran over Arabism. The propping up of "sunni" Arabs in Iraq was a deliberate policy of the Ottomans, and later the British, to counter Iran's influence. Later, the favored sunni Arabs came to hold the political upperhand in Iraq and continued doing so until the US invasion of Iraq. Eventually, if outsiders stop trying to cause problems, most of Iraq will fall into its natural domain and ally itself with Iran even more strongly than under US occupation. The Western regions of Iraq, on the other hand, will have to find a new arrangement since they will not like being close to Iran.
Bush didn't understand that democracy doesn't always go your way, especially democracy under the gun. So what good is democracy in Iraq now after 110,000 deads? The sad part is that Bush has not excuse to accuse them doing anything because now it's a "democracy". A big for Bush.
