Pat Buchanan's Churchill, Hitler, and the Unnecessary War
While Buchanan pointed out some things about Churchill that evades the common opinion of the man, most of his entire book were blanket statements based on his personal opinions and not actual fact.
Aw, come on, you may disagree with his conclusions, but Pat's books are always well-researched and supported.
Perhaps, he did make some serious points, however I failed to see much of a coherent argument. He claims to be a supporter of Reagan in the book and then shows a clear lack of understanding his beliefs.
While some of the ideas exposed were noticeably ill-adept for Britain, most of those shown (Excluding the Anglo-Japanese Alliance and some others) were pretty much preordained. The really interesting part was an expose on Churchill's Keep England White Ideas.
