Jimmy Carter is commonly depicted as one of America’s worst presidents. His four-year tenure is said to be a mishmash of screw-ups, from high energy prices and even higher inflation to low economic growth and a very public, very embarrassing hostage rescue attempt in Iran. His signature achievement, the 1978 Camp David Accords, which codified peace and normalized diplomatic relations between Egypt and Israel, is treated as a small stretch of fresh pavement in an otherwise potholed road.
