2. It was a busy news day regarding Iran.

Our reporters, struck by the country’s two recent satellite launch failures, sought out more than a half-dozen current and former government officials who have worked on the American program to sabotage Iran’s missiles and rockets over the past dozen years. Above, Iranians visit a weaponry and military equipment exhibition in Tehran last week.

The officials revealed that the Trump administration was accelerating efforts to thwart Iran’s missiles and rockets, by covertly slipping faulty parts and materials into its aerospace supply chains. The Trump administration maintains that the Iranian space program is a cover for attempts to develop powerful ballistic missiles that could deliver nuclear warheads.

Separately, a former U.S. Air Force counterintelligence agent was charged with espionage after she defected to Iran. She is accused of helping the country’s elite Revolutionary Guards target her former U.S. colleagues.
