@Drnaline,
Wow, you guys figured this out a good 20 or so years after it occured to the
likes of Osama Bin Laden!
Shi'ia vs. Sunni, should have worked in out favor, but it isn't.
Iraq was a blunder: Hussein and his clique were the good old fashioned secular Arab nationalists... able to be reasoned and bargained with (and we'd done it tons in the past, selectively overlooking what we didn't care for) but mainly no more tolerant of the extremist fundamentalist Islamists than we. Saudi Arabia and some of the U.A.E. have a bubbling underground of radical Islamists who oppose the U.S., and to a certain extent their own rulers, and they're egged on by the clerics, who are employees of the state. So, the friendly government is fomenting U.S. dissent in their own country. Why? To distract the populace from the way the ruling family is robbing the national treasury blind. The Saudi people are kept ignorant and oppressed by Islam, and have a finger pointed at the west if ever they question the reason for their condition. Iran, other the other hand, is more like pre-invasion Iraq. There is an educated middle-class. Most are moderate in their views. The big difference between the two is that the rulers of Iran are extremists, who believe they are on a holy mission to do their distorted interpetation of the wishes of Allah.
So, should we have removed Hussein, who was evil... don't get me wrong, but could've been bought if it was in his personal best interests, or should we have positioned ourselves and aligned international support for addressing the growing threat in Iran? At this point the military isn't exactly in prime shape.
For that matter, should we consider if a country is an ally based solely on the opinions of their leaders or the citizenry? Can you change leaders more quickly than the opinion of the people?
