But nine months earlier, in the wake of U.S. and Israeli strikes on Iran in June 2025, the message coming from Washington was that Iran’s key nuclear facilities had been “obliterated.” Drawing on new reporting, satellite imagery analysis and interviews, this investigation is an updated presentation of our December 2025 documentary by the same name. In September of last year, directors Adam Desiderio and Sebastian Walker, who is also the film’s correspondent, visited sites hit in the June 2025 U.S.-Israeli strikes and sat down with one of Iran’s most powerful officials, Ali Larijani — in what turned out to be the last on-camera interview he gave to an American news outlet before his assassination earlier this month in an Israeli airstrike. Since the current war began, the team has been talking to experts and officials and analyzing satellite imagery with The Washington Post, Bellingcat and Evident Media to try to understand the truth about what remains of Iran’s nuclear program. Their findings offer valuable insights into a continuing conflict that has rippled across the Middle East, killing thousands — including children at an elementary school — and displacing millions. “Strike on Iran” is a FRONTLINE production with Mongoose Pictures in association with The ‪@WashingtonPost‬ ‪@evidentmedia‬ and ‪@bellingcatofficial‬.
