Obama is the father of the Iranian drone program. One can also say, he funded the program.
In December 2011, Iran captured a U.S. RQ-170 Sentinel stealth drone (a highly advanced, radar-evading unmanned aerial vehicle operated by the CIA). The event occurred around December 4–5, 2011, when the drone was on a surveillance mission near the Afghanistan-Iran border. It entered Iranian airspace (likely due to a malfunction, according to U.S. accounts), and Iran claimed to have brought it down intact using electronic warfare or cyber means, landing it with minimal damage near Kashmar.
The U.S. initially avoided confirming details but later acknowledged the loss. On December 12, 2011, **President Obama** publicly stated that the U.S. had formally asked Iran to return the drone, saying, "We've asked for it back. We'll see how the Iranians respond." Iran refused, viewing it as spoils from a violation of their airspace, and paraded it on state TV. Iranian officials said they would not return it and even claimed to be reverse-engineering the technology (which they later used to develop similar drones like the Shahed series).
The U.S. position was that the drone suffered a technical failure and glided into Iranian territory unintentionally—no shoot-down occurred, per official accounts. Iran, however, touted it as a major intelligence and technological coup.
This became a point of tension in U.S.-Iran relations at the time, with no recovery of the drone for the U.S.
