I am curious to see if he mentions it. I don't think he would defend it as much as he would lie about almost every aspect of it, but I also think he would need to be very careful how he covers that part of his life. His legal actions in Croatia won't amount to anything, but if he makes false and defamatory claims in his book, he might be on the other side of a legal case. And if he is selling his book internationally, his sales from the book could be within easy reach of a plaintiff looking to collect on a judgment.
And there is also the issue that others apparently have more pictures and messages that he would not want to be made public. Information that could wreck his attempt at salvaging his reputation. Does he really want to risk that? For a book that won't make much money?
