 Pentecon papers had also another fallout that it led to Nixon and Kissinger, you have quoted Kissinger on his being called the most dangerous man in the world, that they thought that they also knew about nuclear weapons and the possible use of nuclear weapons as had been planned by the United States in against Vietnam. In fact, Nixon had threatened a number of times using nuclear weapons against Vietnam in the war in order to bring them to the table as a threat but also as a real possibility. So they were worried that might leak out and that could explain the kind of paranoid reaction that Nixon had against him because it led to a forming of a group of people, a bunch of people who actually barred, burgled his psychiatrist office because they didn't discover anything they could blacken him with but they left the trail and this is the one which later on is the group which also does the Watergate break-in.
