I disagree that Henry Kissinger was a co-conspirator with the blatant act of treason committed by Nixon during 68 election. I have never seen any account which suggested Kissinger was a party to something that irresponsible. Nixon's actions resulted in  a sickening number of additional causalities and extended the war by six years. I agree the War became a rallying cry for many cracks in the American society which had lingered for decades. However, I don't believe it was the Vietnam war which caused those cracks. The real problem with American society has always been slavery and the after effects of that social institution. It has never  been constructively resolved and its impact on race relations in America has undermined everything good about that country. The Vietnam era only aggravated the racial divide. I do believe that Vietnam was the cause of the election of Ron Reagan and the rise of the NRA which later evolved into the Tea Party and in 2016, the current administration.
