It's been a big year for declassified documents. First we learned secrets about Pinochet, and now newly released tapes by LBJ reveal just how much Nixon was willing to damage the U.S. in order to further his own career. Here's the BBC article, "The Lyndon Johnson tapes: Richard Nixon's 'treason':"
Declassified tapes of President Lyndon Johnson's telephone calls provide a fresh insight into his world. Among the revelations - he planned a dramatic entry into the 1968 Democratic Convention to re-join the presidential race. And he caught Richard Nixon sabotaging the Vietnam peace talks... but said nothing.
It begins in the summer of 1968. Nixon feared a breakthrough at the Paris Peace talks designed to find a negotiated settlement to the Vietnam war, and he knew this would derail his campaign. He therefore set up a clandestine back-channel involving Anna Chennault, a senior campaign adviser. At a July meeting in Nixon's New York apartment, the South Vietnamese ambassador was told Chennault represented Nixon and spoke for the campaign. If any message needed to be passed to the South Vietnamese president, Nguyen Van Thieu, it would come via Chennault. In late October 1968 there were major concessions from Hanoi which promised to allow meaningful talks to get underway in Paris - concessions that would justify Johnson calling for a complete bombing halt of North Vietnam. This was exactly what Nixon feared. Chennault was despatched to the South Vietnamese embassy with a clear message: the South Vietnamese government should withdraw from the talks, refuse to deal with Johnson, and if Nixon was elected, they would get a much better deal. So on the eve of his planned announcement of a halt to the bombing, Johnson learned the South Vietnamese were pulling out... Publicly Nixon was suggesting he had no idea why the South Vietnamese withdrew from the talks. He even offered to travel to Saigon to get them back to the negotiating table.
To me, that seems almost as bad -- if not worse -- of a crime than Watergate: deliberately sabotaging peace talks in order to help your political campaign.
Anyway, to get more background on Nixon, try Thomas Mallon's novel Watergate
In Watergate, Thomas Mallon conveys the drama and high comedy of the Nixon presidency through the urgent perspectives of seven characters we only thought we knew before now, moving readers from the private cabins of Camp David to the klieg lights of the Senate Caucus Room, from the District of Columbia jail to the Dupont Circle mansion of Theodore Roosevelt’s sharp-tongued ninety-year-old daughter (“The clock is dick-dick-dicking”), and into the hive of the Watergate complex itself, home not only to the Democratic National Committee but also to the president’s attorney general, his recklessly loyal secretary, and the shadowy man from Mississippi who pays out hush money to the burglars.
UPDATE: a well-written review of Mallon's book can be found at Blogging for a Good Book.
