Cyberattacks on Iranian nuclear program were a US-Israel effort started under the Bush administration and continued by President Obama, The New York Times reports.
The confirmation from Obama-administration officials that Stuxnet was a joint US-operation comes from extracts from a forthcoming book, Confront and Conceal: Obama’s Secret Wars and Surprising Use of American Power, by David Sanger that’s due to be published next week.
