A nun, a veteran, and a house painter walk into a federal nuclear installation. There is no punchline, because it is no joke.
The three unarmed pacifists who broke into a federal uranium storage area in Tennessee four years ago were making a statement. And along the way, making some points about nuclear security in America.
The incident is the centerpiece of Washington Post reporter Dan Zak's book Almighty, about the nuclear age and all it has meant to Americans. Anyone who remembers an air-raid drill from elementary school can relate.
