Iran has said that it is not developing a nuclear weapon, and quarterly inspections by the International Atomic Energy Agency support this claim. Moreover, two National Intelligence Estimates, compiled in 2007 and 2011 by America’s dozen and a half intelligence agencies, say Iran stopped work on a nuclear weapon in 2003. Finally, according to Wikipedia:
On ideological grounds, a public and categorical religious decree (fatwa) against the development, production, stockpiling and use of nuclear weapons has been issued by the supreme leader of the Islamic Republic Ali Khamenei along with other clerics, while it is supported by others in the religious establishment.(As president Ahmadinejad has no authority over Iran’s military.)
Bachmann of course has zero chance of getting the Republican presidential nomination, but her repetition of this vicious lie could be effective in scaring the American people into supporting the other forces drumming up support for war against Iran. These include the neoconservatives, Israel, and the Israel lobby.
