What was the general perception of Nazi Germany among Americans pre-WWII? Did they see them as suspicious, just another country, or a role model to look up to? What were the most popular opinions of the time?
What did Americans think of the Olympics? Did they find them oppressive and imposing, or were they considered something to marvel at and strive for?
I decided to look at the New York Times archives for my research. Understand that this is only one source, though it was and still is considered quite reputable. I did not look into the opinions surrounding the Olympic games held in Germany in 1936, preferring instead to go for a more overarching look at the articles being written about Germany in this time period.
I specifically searched for mentions of Germany between 1 January 1933 and 1 October 1939. On the first several pages of results, articles resembling what we see today about Russia and North Korea come up regularly, with many articles about major reparations news stemming from the end of the first world war.
One article from the March 13, 1933 edition of the NYT was entitled "Two More Americans Beaten By Bands of Nazis in Berlin", another from November 10, 1933 is entitled "German Digs at Us Cause Consul to Leave Meeting".
These articles both discuss transgressions against Americans or US diplomatic representatives in ways that reflect the actions we see in Russia or North Korea today. They’re largely news about a country that is becoming more and more reclusive, and building itself into something that the world does not seem to want it to be.
As I moved from 1933 towards 1939, I began to see more articles mentioning international political happenings: speeches from Neville Chamberlain, mentions of Goebbels controlling media outlets, and news of German military technologies, such as an article from March 21, 1939 entitled “Reich Claims Bomber Goes 323 Miles an Hour”.
This is by no means an exhaustive review of the source materials available, but as a general answer to your question, it seems that Germany was viewed with apprehension and some distrust. In addition, there seems to have been a genuine hope that more conflict could be avoided by ignoring or placating the Reich. This is, again, not dissimilar to what we see today with news about Russia and/or North Korea.
