If you want to understand the U.S.-Iran controversy, know this: It is not about nuclear weapons.

You're thinking: Of course it's about nuclear weapons. Everyone says so.

Well, not everyone does. But it isn't a numbers game. As William O. Beeman points out in the Huffington Post:

"There is a strange irony in President Obama's announcement of the temporary agreement. He mentioned the term 'nuclear weapon' multiple times in his announcement, implying that Iran was on a path to develop such a weapon. One wonders if he actually believes this or if his repeated implied accusation was a rhetorical device designed to placate his hard-line critics.

"The president must know by this time that there is no evidence that Iran has or ever had a nuclear-weapons program. Every relevant intelligence agency in the world has verified this fact for more than a decade. U.S. National Intelligence Estimates that were made public in 2007 and 2011 underscored this. The International Atomic Energy Agency has also consistently asserted that Iran has not diverted any nuclear material for any military purpose.

"Even Israeli intelligence analysts agree that Iran is 'not a danger' to Israel."
