Assuming that this is true that Richard Nixon was negotiating with North Vietnam, the Communist Republic of Vietnam back then, as a private citizen without the permission of the Lyndon Johnson Administration, then you can add that to the long list of charges and real felonies that any other American would’ve done at least twenty-years on in prison for. Assuming the prosecution decided to prosecute Dick Nixon on all of those charges. And if this is true, then Nixon became a criminal before he became President of the United States.
And this is two or three years before Watergate and a couple of years before the plumbers unit was installed in the Nixon White House. The plumbers and the criminal operations inside of the Nixon White House was the real crimes of the Nixon White House. What Watergate did, well actually what the Nixon coverup of Watergate did, was to blow open all the illegal operations of the Nixon White House. That would’ve gotten President Nixon impeached by the U.S. House in 1974 and most likely convicted by the U.S. Senate in the same year as well.
What the Nixon campaign did in 1968 and then of course the plumbers unit in the White House in the early 1970s, there’s no way they would’ve gotten way with that today. And probably not in the 1990s and perhaps not the 1980s as well. Because they were holding so many secrets and trying to plug so many holes. And those holes would’ve broken in the information revolution of cable news and the internet. And people in the White House quite frankly, trying to save their asses.
