I don't subscribe to unvarying set of strategies and tactics, either on a temporally longitudinal basis or across theaters and discrete sets of problems. Further, your thinking, inflexible on its face, would necessarily occasion the same errors of the past, except in mirror image. And I don't have to tell you that not only was your selection of examples tendentiously incomplete but that it is belied by the prime example of them all, recently: the Cold War, the reason for our foray into Vietnam, came to a crashing conclusion in our favor (without a shot fired) some 15 years or so after our ignominious defeat in and withdrawal from Vietnam.
