Like they conveniently forgot the last time someone tried that. Now, I don't know what to make of it. I got some footage of what happened with Rodan— [...] But, I don't know if anyone else did, or how much they caught. But if you ask me? Dangerous as Monster X might be, I... well, I think she was just scared. I've interviewed a lot of people since last year, couple of them flew at me because I got stupid and said the wrong thing, and I don't know why but that mess from yesterday reminded me of that.''"

->''"Even a small, inept street-fighter has a tremendous advantage over the average middle-class American, who hasn't had a fight since puberty. It is a simple matter of accumulated experience, of having been hit or stomped often enough to forget the ugly panic that nice people associate with a serious fight. A man who has had his nose smashed three times in brawls will risk it again with hardly a thought. No amount of instruction in any lethal art can teach this -- not unless the instructor is a sadist, and even then it would be difficult because the student's experience would be artificially warped and limited.\\\
San Francisco is a big karate town: in 1965 there were roughly seven thousand full-time fee-paying karate students roaming around the Bay Area... but in any active bar you can hear a story about a bartender who "busted up a guy who tried to pull some karate stuff." It hardly matters how many of the stories are true. The point is valid: the difference between survival and wipe-out in a physical crisis is nearly always a matter of conditioned reflexes. A bartender with scar tissue all over his knuckles will hit faster and harder than a karate-trained novice who has never been bloodied. For the same reason, a Hell's Angel who has been over the high side often enough to joke about it will ride a motorcycle with a style and abandon that comes only with painful experience."''

->''"Strategy is about adaptation as much as design. There is no universal formula for strategic success. An approach that works beautifully in one scenario can backfire catastrophically an another. The enemy gets a say in war and competition; it will always try to spoil the savviest plans. So, strategy is a never-ending process, one in which flexibility and good judgment are as important as the brilliance of any initial scheme. America’s Cold War strategy, containment, was continually revised and modified over a 40-year period, as conditions changed and the Soviet Union experimented with new methods of expansion. Napoleon’s revolutionary style of warfare nearly gave him mastery of Europe, until his adversaries wised up and changed their own methods. Advantage is perishable, so adaptation is essential."''
