I was watching a DVD the other night, The Fighting 69th, a WWII era movie (set in WWI). One of the bonus features on the disc was a short newsreel about the Nazi bombings of London. The entire feature was about how determined the British were not to let Hitler intimidate them or break their spirit, even as bombs fell on their city every evening. I kept thinking that if this was occurring today, the reporter would be seeking out people who whine and cry in front of the cameras, people who would blame their own country for the bombings and would be screaming angrily about how Churchill should negotiate a "peace" proposal with Hitler because the bombings are just too much to take.
When I was a kid growing up in the sixties, Pearl Harbor occasionally came up as a topic for discussion at home, with the older men sitting around the barber shop, and elsewhere. People were still mad about it, a quarter of a century later. Yet, within a couple of weeks of 9/11, people at my place of employment were complaining that it was still being talked about. The whole attitude was, "Like, okay, 9/11 was a bad thing, but, like, it's over and let's just move on and stop thinking about it".
I don’t see how any American can forget Sept 11, 2001, in only seven years.
