Yes and as I like to say, we've met the quagmire and it is us. Again!
We (the public) knew back then but we were the silenced majority except when it came to elections; to wit, we won 49 states to the Communists' enemy's one state, 1972.) No Internet, no modern talk radio (the "Fairness Doctrine"), no time for a street rumpus, we worked.
Another lesson is: watch out for authoritative "experts" like Ed Moise. To wit, he perhaps rightly states that Gen. Giap did not say such and such --- But! it's documented that at least one member of his staff, Col Bui Tin did say such and such. Why didn't the "expert" refute or acknowledge that? Another Clintonesque Rat?
The Commies have an answer to everything.
