Incoming demoncrat POTUS #1 disregarded a warning from the outgoing Republican POTUS (who just happened to have been the Supreme Allied Commander of the victorious WWII Allied Forces in Europe) not to get involved in a ground war anywhere in Asia.
demoncrat #2 got the US entrenched in demoncrat #1’s war Southeast Asia but lacked the leadership or resolve to win it.
There are surviving recordings of telephone calls made by both demoncrats #1 & #2 in which they remarked that couldn’t pull the US out of the war in Vietnam because it would have have been devastating to their re-election chances.
Then the demoncrats fomented anti-war hatred of the government, which Nixon inherited.
Nixon cut through the crap and ended the war in Vietnam, and for this, he’s remembered as a villian.
Exactly right.
