"Our timetable for withdrawal is more optimistic now than when we made our first estimates in June. Now this clearly demonstrates why it is not wise to be frozen in on a fixed timetable. We must retain the flexibility to base each withdrawal decision on the situation as it is at that time, rather than on estimates that are no longer valid. Along with this optimistic estimate, I must in all candor leave one note of caution. If the level of enemy activity significantly increases, we might have to adjust our timetable accordingly."
Richard Nixon's secret timetable is the best policy I've heard in a long time - he doesn't have to tell anybody anything, so he can never be wrong!
