I never criticized United States planners for mistakes in Vietnam. True, they made some mistakes, but my criticism was always aimed at what they aimed to do and largely achieved. The Russians doubtless made mistakes in Afghanistan, but my condemnation of their aggression and atrocities never mentioned those mistakes, which are irrelevant to the matter -- though not for the commissars. Within our ideological system, it is impossible to perceive that anyone might criticize anything but "mistakes" (I suspect that totalitarian Russia was more open in that regard).
