I actually has psyche written down, and changed it.

It’s not exactly the normal use of zeitgeist and maybe volksgeist would be a better term (except tthat we don’t use it in English), but I feel that this is a relatively new aspect to Americanism, starting in WWII. It’s still more of a growth on their psyche than a fundamental part of it.

It also has some parsllels with British exceptionalism up to the endnof the 19th century
