I went to see Rick Perlstein talk about Nixonland at a book signing last night.
At one point he noted that in private communication in 1966, Nixon said the Vietnam War couldn't be won. And yet he spent the next 7 years Red-baiting anybody who said so, and, once in office, let literally millions of people be killed rather than lose the wedge it made between Democratic voters.
Lying the entire time.
There are obvious parallels today.
Last paragraph in the book:
How did Nixonland end? It has not ended yet.
Updated to correct date, and to add link, via email from Perlstein.
