For unrelated reasons I personally don't believe Iran was ever pursuing a nuclear weapon, just edging enrichment for leverage.

That said, this:

  The US has had two National Intelligence Estimates, which consists of all 18 agencies in the intelligence community, conclude that they were not developing nukes.

has little weight given these were / are the same US intell agencies that were blindsided and caught pants down unaware and in the dark about the 1998 India / Pakistan nuclear test exchange.
