these two challenges by improvements in his methods of conducting war against communists and in vigorous action to build greater popular support. We should help and encourage him to take effective action.

At the same time that Durbrow turned to an emphasis on pressure, his dispatch contained strong hints that U.S. ability to influence Diem and his immediate entourage without pressure might have declined, as an immediate result of the abortive coup and the perceived relation of the U.S. to it.
