There was, sometimes, a de facto alliance between this president and pope. But relations were not so close that they could be taken for granted by the president's men. In fact, the documents reveal a continuous scurrying to shore up Vatican support for U.S. policies.

Following the pattern set by Julius Caesar in The Gallic War, Churchill wrote books to vindicate policy; but he may also have made policy with an eye toward writing books. If so, the implications are alarming. Did Churchill conceive bold operations, such as the disastrous 1915 Dardanelles offensive, because these would make exciting episodes in the text of his life? A. J. Balfour once joked that Winston had written an enormous book about himself and called it The World Crisis. Was there more truth in that joke than we have so far known?

One would think that agents charged with protecting us from "dirty nukes" would enjoy the same discretionary search authority as patrolman who make traffic stops. In fact, they have less. If a patrolman pulls you over for weaving between lanes, and smells bourbon on your breath, he does not need a warrant to give you a breath test. But if an FBI agent learns that you are a member of a known terrorist group, and that you behaved suspiciously at a flight school, he must jump through bureaucratic hoops of fire to search your laptop computer.
