Oh dear, I got away from the main subject, sorry. Homeland attitude- I saw a lot, the hippies, a lot of things. The big difference was that took so long, years, and it was never really resolved. Time will tell how this compares to then.
When I was in high school, we were discussing the Vietnam war (it was the late seventies and it was over by then) One boy almost laughed, saying he remembered hearing the news of Vietnam like it was a football game- 25 US soldiers killed today, 123 Vietcong- our side is winning! I had never thought about it like that until he put it that way, but it was like that for us kids, that's how it seemed. I think it was more distant and surreal for kids, even though we do have memories of it and heard people talking, you probably need someone who's at least 50 now to remember in the terms of a 'grownup.'
One thing I can say is, I never, EVER feared for my own life in my little surburban neighborhood. We had no fear of terrorism, chemical or biological warfare, suicide bombings, or any 9-11 type things. I remember seeing them on TV, in Lebanon, Israel, even Ireland. But we felt very safe in America in those days, and I don't anymore.
