Graphic novel 2020

The book, the graphic novel (and supposedly the movie) are all ==about the Dresden Bombing== (which the author witnessed as an American POW). It is an anti-war book with comic relief, and science fiction to provide an outside perspective. "Billy Pilgrim's come unstuck in time." Please understand the Tralfamadorians had nothing to do with his becoming unstuck in time; they were just able to help explain what was happening to him (and he lived in their zoo on their planet with a sex worker who bore his fourth child). Yes, it's rediculous, but he wanted to get us to listen.

The second name of the story is, "The Children's Crusade," (referencing the Dresden atrocity).

He wanted us All to know how horrible, and meaningless, war is.

==He told his children they should never participate in any massacres.==
