			:The discrepancy is confirmed, and the sourcing hierarchy makes it more serious than a routine rounding disagreement. The lead's "almost one-fifth" cites a 2013 Business Insider article (a secondary write-up); the body uses two primary sources that both point lower: the ISIS December 2010 report (10% / ~1,000 physically destroyed) and, separately, the ISIS February 2011 follow-up (which again refers to "only 1,000 centrifuges"). The FAS operational-decline figure mentioned in the body (~4,700 → ~3,900, or ~17%) is closer to "almost one-fifth," but it measures centrifuges taken offline, not destroyed — a different claim. It is also worth noting that the Washington Post/IAEA paragraph in the same section gives 900–1,000 removed, consistent with the ISIS destruction figure.
			:So the article is simultaneously presenting, without reconciliation: ~17% operational decline (FAS), ~10% physical destruction (ISIS), and "almost one-fifth" (~18–20%) in the lead. The lead figure does not have a primary source that actually asserts it. Rome's proposed fix — updating the lead to reflect the ISIS primary-source figure (~1,000 / 10%) with an inline citation directly to the ISIS report — would resolve the mismatch cleanly. If editors wish to retain the higher figure, a primary source asserting ~20% physical destruction is needed; the Business Insider piece does not supply one.

Lead says 'almost one-fifth' but body's primary ISIS source gives 10 percent (~1,000 centrifuges): new section

New page

== Lead says 'almost one-fifth' but body's primary ISIS source gives 10 percent (~1,000 centrifuges) ==

The lead summarises the centrifuge damage as "almost one-fifth" of Iran's centrifuges, but the body's own primary-source treatment of that damage figure is half that:

* '''Lead, paragraph 2''': "Stuxnet reportedly destroyed '''almost one-fifth''' of Iran's nuclear centrifuges." (cited to a 2013 Business Insider piece)
* '''Body, "Iranian centrifugal damage" / ISIS section''' (citing the December 2010 ISIS report): "...may have destroyed up to 1,000 centrifuges ('''10 percent''') sometime between November 2009 and late January 2010." Followed by an ISIS block quote: "...there remain important questions about why Stuxnet destroyed '''only 1,000 centrifuges'''."

"Almost one-fifth" implies roughly 18–20 percent. The Institute for Science and International Security (the source the body uses to substantiate the centrifuge-damage figure) explicitly puts it at 10 percent / about 1,000 centrifuges. The Federation of American Scientists data the body also cites (decline from ~4,700 to ~3,900, or ~17%) is closer to the body's framing than to the lead's.

The lead is overstating the body's own sourcing by roughly a factor of two — not an interpretive nuance but a numeric mismatch with the article's primary source.

'''Suggested fix:''' change the lead to track the body's primary sourcing — e.g. "Stuxnet reportedly destroyed about a tenth (around 1,000) of Iran's nuclear centrifuges" or, more conservatively, "Stuxnet reportedly destroyed roughly 1,000 of Iran's nuclear centrifuges." If the higher figure is to be retained, it needs a primary source that actually claims ~20%; the cited Business Insider piece is a 2013 secondary write-up.
