...President Bush held one of his private book club sessions that Karl Rove organizes for him at the White House. Rove picks the book, invites the author and a few neoconservative intellectual luminaries, and conducts the discussions. For this Bush book club meeting, the guest was Andrew Roberts, an English conservative historian and columnist and the author of "The Churchillians" and, most recently, "A History of the English-Speaking People Since 1900."

The subject of Winston Churchill inspired Bush's self-reflection. The president confided to Roberts that he believes he has an advantage over Churchill, a reliable source with access to the conversation told me. He has faith in God, Bush explained, but Churchill, an agnostic, did not. Because he believes in God, it is easier for him to make decisions and stick to them than it was for Churchill. Bush said he doesn't worry, or feel alone, or care if he is unpopular. He has God.
