" On the question of the machinery of government, we have seen that a good deal of our trouble seems to have stemmed from the extent to which the executive has felt itself beholden to the short-term trends of public opinion in the country and from what we might call the erratic and subjective nature of public reaction to foreign-policy questions. I would like to emphasize that I do not consider public reaction to foreign-policy questions to be erratic and undependable over the long term; but I think the record indicates that in the short term our public opinion, or what passes for public opinion in the thinking of official Washington, can be easily led astray into areas of emotionalism and subjectivity which make a poor and inadequate guide for national action.
