Three complete chapters
Not samples. Whole chapters, formatted the way the book reads them — the war story at the top, the honest counterargument near the end, and the closing thread. If you don't like these, you won't like the other twenty-eight, and that is a useful thing to find out for free.
The full table of contents — all thirty-one chapters, with the closing thread of each — is on the contents page. It is the fastest way to see whether the book has anything you need.
