Questions about Iran's nuclear program have been swirling for years causing fear in the west that they are secretly preparing to build a nuclear warhead.
Iran has steadfastly maintained that their nuclear ambitions are only for the purpose of energy production, and that they have no plans to enrich uranium for the production of nuclear weapons.
However, a new IAEA 25-page report, a decade in the making, says there is credible evidence to make a case that "Iran has carried out activities relevant to the development of a nuclear device."
This is some of the most damning evidence ever released about Iran's nuclear interest, but Iran has blasted the report, calling it politically motivated by the west, and an excuse to carry out military action against Iran.
While the report does not claim that Iran has the technology to produce a nuclear weapon yet, it does site evidence that Iran "had been provided with nuclear explosive design information" as well as computer modeling of nuclear detonations.
On Around the World, Christiane Amanpour speaks with the New York Times' David Sanger to take a deeper look into this report which could have a worldwide impact, effecting not only the United States and Iran, but also putting pressure on Iran's allies China and Russia.
