I only see him calling this a small war compared to what the USA could have brought to the battle field. At the peak, there were about 550,000 US troops in Vietnam. In World War Two, they eventually fielded 10 million persons (https://warfarehistorynetwork.com/2017/06/26/us-involvement-in-wwii-how-the-military-grew/ https://warfarehistorynetwork.com/2017/06/26/us-involvement-...). So, if the political will had been there at home, they could have sent a lot more. I also think what you describe in “Congress and Senate couldnt… made it equally untenable at home.” is precisely the argument this paper made: that war was lost in the USA, not in Vietnam.
