Great book on Nixon's conduct in office, helped along by declassified documents and released tapes not available to contemporary accounts.

Amazing how much the Vietnam War was a madness rune for both LBJ and Nixon, feeding their worst instincts and creating the impression they were under siege. Just a complete total impotence of power unlike anything else in their experience. And for Nixon, in particular, the Vietnam paranoia directly led to the Watergate paranoia, connected by the Ellsberg break-in and much more.

It's a great book, but just go in knowing it doesn't cover much outside the White House, disregarding the political for the procedural. Still, great for girding books on the other subjects since it's pretty recent, and has a lot of documentary evidence unavailable to earlier authors.
