A New York Times story adapted from the book, “Confront and Conceal: Obama’s Secret Wars and Surprising Use of American Power,” quotes participants in secret White House meetings discussing plans to unleash Stuxnet on Iran.

The scores of State Department emails from the fall of 2011 to the spring of 2012 do not reveal which officials told Mr. Sanger, but they do show an atmosphere of cooperation within the administration for a book generally favorable toward, but not uncritical of, President Obama. For example:

“I’m getting a bit concerned about the pace of our interviews — or lack of pace, to be more precise — for the book,” Mr. Sanger said in an email Oct. 30, 2011, to Michael Hammer, a senior State Department public affairs official. “The White House is steaming away; I’ve seen [National Security Adviser Thomas E.] Donilon many times and a raft of people below. Doing well at the Pentagon. But on the list I sent you starting on Sept. 12 we’ve scheduled nothing, and chapters are getting into final form.”
