Most assuredly. At least in Europe, the younger generation has older relatives that have been in serious conflicts within their own borders, within those older relatives’ lifetimes. And many of those nations still bear the scars of those conflicts. I remember traveling across the Gulf Coast (primarily Mississippi) in 1971 on my way from one military assignment to another, and being in absolute awe of the power of hurricane Camille – two years earlier! The devastation was still quite apparent. But that was relatively easy to think about, because it was “just” caused by weather – not other human beings on a massive scale. We can write off occasional riots and disturbances, such as Watts or Ferguson, because those don’t represent the experience of most Americans – they’re just news events on TV. Only if we happen to actually know or later meet someone that was intimately involved in those tragedies do they take on any personal meaning to us. So yes, Americans have for the most part been marvelously sheltered from large-scale human tragedy, and particularly personal hunger and even survival concerns. We’re too many generations removed from it to be even remotely ready to cope with it. Good observation.
