Like you, I don't change my mind that often. However, all my opinions are provisional and may change based on new information. So, thanks for the new information.
I might be interested in reading Pape's book, although I'm a bit dubious about his thesis that all of these types of terrorist acts fit into a particular model (at least, that's what I understand his thesis to be). But it sounds like a good candidate for the non-fiction category.
