In April 1980, frustrated with the slow pace of diplomacy (and over the objections of several of his advisers), Carter decided to launch a risky military rescue mission known as Operation Eagle Claw. The operation was supposed to send an elite rescue team into the embassy compound.

Eight American servicemen were killed in the accident, and Operation Eagle Claw was aborted.
