Talk:Stuxnet

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. Rome (talk) 00:32, 29 April 2026 (UTC)
