I've always been a fan of the 'worst person becomes the hero' trope.

See 'Incorruptible' comic

And yes, Red Sun may be the best Superman comic ever written.

Jimmy Carter was an atomic engineer.

In 1953, after his father’s death, Carter resigned from the Navy to return to Georgia. However, his nuclear expertise was called upon in 1958 when Canada’s Chalk River nuclear research facility suffered a partial reactor meltdown . The incident caused a power surge that damaged the reactor core and flooded the basement with radioactive water.

Carter was sent by the U.S. to lead a cleanup team. He and 22 others worked in teams of three, descending into the reactor for only 90-second intervals to avoid lethal radiation exposure. To plan the operation, they built a full-scale replica of the reactor (without nuclear material) on a nearby tennis court. Carter’s leadership under extreme conditions demonstrated his technical competence and composure.

Never read that one.

otoh, they did start a war with Canada in "Canadian Bacon"

And a war with Canada is actually smarter than one with Iran.

Canadians are used to forgiving stupid Americans.
