Here is how one of todays top scholars views Chomsky's methodology.
Huntington commented on Chomsky’s claims thus (NYRB, 26 February 1970):
It would be difficult to conceive of a more blatantly dishonest instance of picking words out of context so as to give them a meaning directly opposite to that which the author stated. For the benefit of your readers, here is the "obvious conclusion" which I drew from my statement about the Viet Cong: …the Viet Cong will remain a powerful force which cannot be dislodged from its constituency so long as the constituency continues to exist. Peace in the immediate future must hence be based on accommodation.
By omitting my next sentence — "Peace in the immediate future must hence be based on accommodation"—and linking my statement about the Viet Cong to two other phrases which appear earlier in the article, Mr. Chomsky completely reversed my argument. (Incidentally, the phrase "direct application of mechanical and conventional power" is not mine, but one which I quote from Sir Robert Thompson. Mr. Chomsky, however, does not see fit to recognize these distinctions of authorship.)
Mr. Chomsky's further effort to say that I favor demolishing Vietnamese society and "eliminating the people" in order "to crush the people's war" is totally false and misleading. My article described the urbanization produced by the escalation of the war between 1965 and 1968 and the extent to which this "American-sponsored urban revolution" undercut the "Maoist-inspired rural revolution." It concluded from this fact that peace would require compromise and accommodation on both sides. To eliminate Viet Cong control in the areas where they have been strong, I said, "would be an expensive, time-consuming and frustrating task." Instead of attempting this, we should aim at a political reintegration of the country which "clearly will depend, however, upon the recognition and acceptance of Viet Cong control of local government in these areas. It is here that accommodation in the most specific sense of the word is a political necessity." This is, in a nutshell, the thesis of the article, and it is well reflected in its title, "The Bases of Accommodation," which Mr. Chomsky somehow forgot to mention.
