I've read the books Nixon wrote from the 1980's on and they are very insightful and brilliant on foreign policy especially. (By the way, I've read stories that Nixon was a superb poker player and during his stint in the US Navy during World War II, his winnings from playing poker were often sent back to financially help his mother.) His final book, Beyond Peace, was just brilliant in his insights on the state of the world.
As someone whose mother made me a news and political "junkie" at an extremely young age, I can tell you all about Nixon's political history, in detail. He WAS brilliant and yes, his books, which he DID write, are AMAZING!
Teddy imagines that he is Reagan and maybe also Nixon, when he is SO unlike both men, it's shocking. He has NO common sense, no political skills at all, and no vision at all....NONE! Neither does he know anything at all about geopolitics.
