Aren't you just providing the details behind his assertion? The US was not willing to prosecute total war in order to win and it lost the will to fight a protracted guerrilla campaign. The British won their war in Malaysia using more overwhelming numbers and cutting off access to the villages by the guerrillas. It took about 10 years if I recall. It also takes a good 10 to 1 manpower advantage to pull this off. The US wasn't willing to make that commitment and the US population lost patience. News reports and general agitation by those opposing the war raised the public's consciousness about the war and how it was being prosecuted. (Interesting factoid, even though at the peak we had over 524000 service men and women in Vietnam, only 80,000 had direct combat roles. That' the same number the French had with only 140,000 + soldiers.) The French didn't have golf courses and pizza delivery by helicopter.
