Certainly an interesting and engaging read. U.S. presidents, like all historical figures, are always far more complex than any one narrative presented about them. Nixon is perhaps the definition of this rule. Here are a few thoughts:
First, he is defensive for all of the obvious reasons; about Watergate, about policy, about his public persona, about his decision making. That is to be expected in an autobiography. Supporters will appreciate his "setting the record straight," while detractors will say he is just trying to justify his shortcomings and cement a legacy. Historians will listen, but they will also check the receipts. Listening to Nixon defend himself reminded me of the David Frost interviews (of which I have endured all 7 or 8 hours). There is nobody in front of you seeking clarification or pressing you for a straight and honest answer in the autobiographical format. Presidential autobiographies are important historical documents, but you always have to listen to them with a sense of inquiry.
Second, despite modern conservatives aligning themselves with a "Nixonian" worldview, I'm not sure they really have. I'm not sure many modern conservatives really understand Nixon beyond the Southern Strategy, the Silent Majority, Vietnam, and Watergate. This follows something I noticed in my reading of Barry Goldwater last year.
Additionally, there are gaps here. Massive gaps sometimes. Difficult topics are left to the side. The cultural challenges of the 1960s are footnotes more than passages here. The topics selected felt cherry-picked to put a best foot forward.
Finally, reading Nixon's words reminds me of something I thought reading Jimmy Carter, Barack Obama, Herbert Hoover, and a few other presidential autobiographies; these people have the absolute most unique perspective of the United States. Post-presidency, they are allowed to step away from all of the controversy and venom of politics to become these sage elders who have seen the best and worst in our country and have gained knowledge from those experiences. No longer restrained by policy, polls, or advisors, they are allowed to become idealistic.
Even quotable passages here were moments that felt simultaneously inspirational and contradictory to the Nixon I've studied as a political figure.
Historians will never be kind to Nixon's presidency, as well they probably shouldn't. Watergate (and Vietnam) created a deep cynical divide in our nation that has only developed further. That said, we are all more complicated than our best or worst decisions, and Nixon's own voice presenting nuance to his life, and political career is an essential element of the overall historical narrative.
