In the weeks since the U.S. and Israel began bombarding Iran, President Trump repeatedly justified the strikes by claiming Iran had posed an imminent nuclear threat.

Drawing on new reporting, satellite imagery analysis and interviews, FRONTLINE, The Washington Post, Evident Media and Bellingcat investigate the status of Iran's nuclear program amid the second round of U.S.-Israeli military action in less than a year.
