Utter nonsense! These people knew this was Jimmy Carter's book, and they must have known what his viewpoints are. What did they expect to read? Anyway, you can't go round suing people because you consider their viewpoints or version of what happened to be a "lie". Where would that end?
The way to deal with this is to set the record straight, or rebutt the arguments put forward by the author. In other words, don't censor Carter. Write a better book.
You state;
“The way to deal with this is to set the record straight, or rebut the arguments put forward by the author.”
What better place than in a court of law with the whole World watching Jimbo defend his lies!
