If you're looking into Nixon and that time period, another little angle you may want to toss into that dumpster fire of "history" is the fact that the Pentagon did not trust him and was spying on him (quelle surprise!):

Nixon and the Chiefs (The Atlantic, April 2002)

The Atlantic's spin, of course, is just more Nixon blackwashing, but you can gain insight by reading carefully. Take a look at this quote:

In his 1976 memoir, On Watch, Admiral Zumwalt lamented "the deliberate, systematic and, unfortunately, extremely successful efforts of the President, Henry Kissinger, and a few subordinate members of their inner circle to conceal, sometimes by simple silence, more often by articulate deceit, their real policies about the most critical matters of national security." Scarcely alone in his views, Zumwalt marveled "that rational men could think that running things like that could have any other result than 'leaks' and 'spying' and all-around paranoia." Indeed, he said, "they had created a system in which 'leaks' and 'spying' were everyday and essential elements."

I read this as an excellent illustration of the mindset of Deep Staters: To themselves and each other, they are the true heroes of this story. They are the rational ones, the patriotic, those who have the will to do that which is necessary, which they must do in secret because (the unspoken part) the masses could not possibly understand.

It never, ever occurs to all these Deep State types that if they were elected President, they would not tolerate Pentagram fuckwads who were certain they knew better spying on and undermining them.
