"Before July 2015, Iran had a large stockpile of enriched uranium and almost 20,000 centrifuges, enough to create eight to 10 bombs, according to the Obama administration.

The agency's director-general, Yukiya Amano, said the report concluded that until 2003 Iran had conducted "a co-ordinated effort" on "a range of activities relevant to the development of a nuclear explosive device"."
August 30, 2012: The IAEA reports that Iran increased the number of centrifuges installed at the Fordow enrichment plant and is continuing to produce uranium enriched to 20 percent in excess of its needs for the Tehran Research Reactor.
There are numerous indications that Iran did not live up to the deal for many years from credible sources that are NOT American.
