In this book the author comes across as a bit of a cross between Terry Prachett, Jeremy Clarkson and Kurt Vonnegut (in the Breakfast of Champions
sense). While a lot of the writing is bordering on the surreal, the points are both generally funny and often thought provoking. The fact that he is a Republican does not come through particularly strongly, or put differently, it does not diminish the enjoyment of the book overall.
He manages to portray the futility of war, the relative lack of understanding and patience of Americans, when it comes to foreign policy, and to provide pages of witty commentary from various hotspots around the world.
Where the book lost the fourth star for me is in the chapter on Nobel Prize winners and their attempt at a peaceful message. While nothing in the chapter was wrong per se, I felt the author lost his detached cool, which makes him funny and endearing and appeared relatively shrill. This chapter was of such markedly different (lower) quality in my eyes that it definitely lowered my appreciation of the book overall - not that it was in any way essential to it, either.
While the author definitely does a good job of political satire, I personally enjoy him more when he is writing about cars and driving - something which is exactly the opposite with Jeremy Clarkson, who really should write about anything but cars.
