To me, it’s the point where directions turn that are key. To others, it’s the point at which that turn seeks validation, when it’s challenged, that matters.
So to me 1968 matters more than 1976, and 1932 more than 1940. I think 1896 was a key year for America, and that 1860 was probably the key moment in our entire history.
But others just see directions set in those years. The real crisis, in their view, comes after, when the new assumptions are challenged and things turn really violent. World War II is on The History Channel a lot more than the Great Depression is.
