Michele Bachmann said that Iran has a plan in the works to split Iraq with another entity, in which it will take over the northern half of Iraq and turn it into a terrorist breeding ground. She refused to source that statement; my guess is that she knows that if she tells people God whispered it in her ear, people will realize how batshit insane she is.
Of course, there’s a broader principle here. Even a lunatic like Bachmann doesn’t make things up unless they’re part of radical right-wing dogma. She’s hardly the only creationist in Minnesota. There is a real Iran, and there’s the Iran various ideologues want there to be. For the extreme left, it’s thriving and governed by a popular regime. For the extreme right, it’s an omnipotent terrorist state preoccupied with nothing but killing Americans and spreading Jihadism.
For people like Bachmann, it’s self-evident that Iran is and has always been this sinister enemy. In the real world, Iran was part of the USA’s war on terror until Bush wrote it off as a member of the Axis of Evil; but in American right-wing fantasies, it’s always supported every Jihadist organization, even Sunni ones like Al Qaida. In the real world, Iran is plagued by a looming oil peak and rock-bottom regime support; in American right-wing fantasies, it’s capable of taking control of the northern and western half of Iraq – i.e. the Sunni and Kurdish parts, where it’s even more hated than the US.
