In June 2017, the United States State Department's Office of the Historian released its revised historical account of the event. The volume of historical records "focuses on the evolution of U.S. thinking on Iran as well as the U.S. Government covert operation that resulted in Mosadeq's overthrow on 19 August 1953". Though some of the relevant records were destroyed long ago, the release contains a collection of roughly 1,000 pages, only a small number of which remain classified. One revelation is that the CIA "attempted to call off the failing coup but was salvaged by an insubordinate spy." The reports released by the U.S had reached 1,007 pages, consisting of diplomatic cables and letters according to VOA News.
