Should of added the option


'Iran would still be rising at this magnitude, even without the 2003 US invasion. But ISIS will Not'


Iran is an oil exporting based economy so its not the Iraq war would of affected them.


On the otherhand, the Iraq War was one of the distant cataylst for the rise of ISIS amongst the Sunni population upset with losing their saddam era privileges.

It is an option.

And most of Iran's rise has been possible due to filling the vacuum left by Saddam Hussein, especially in Shia lands.
