Well so was I, which was why I asked the question.
The answer to your question above is "the same way".
Americans are "dealing with the threat of war" the same way Germans did in the time leading up to World War Two. They're dealing with it by immersing their sensory inputs past the overload point, and using that process to keep the denial engines running flat out.
Life is a cabaret.
It is just too wide of a brush to paint the entire population of United States.
I do not see the comparison between the people portrayed in Cabaret (Germany of the late 1930s) and United States of 2002.
