Panetta was on Meet the Press this morning. He said the Iranians are not building a bomb, but they are "increasing their nuclear capability."
What's really happening is the Iranians are working on purifying fissionables to weapons grade but may not have not started fabrication of the subcritical masses, the implosion sphere, or the bomb casing. Big deal.
But the first part of Panetta's statement "the Iranians are not building a bomb." is a clear falsehood.
