The paragraph after your last quoted paragraph reads:
Their greatest danger to this country lies in their large ownership and influence in our motion pictures, our press, our radio and our government.
That's a well-worn antisemitic slur.
I don't know. It may be more a home truth than a slur. I look at the accomplishment of the Jews and am filled with admiration and gratitude. (Thank you, Dr. Salk!) Others with envy and resentment.
I would like to see where Lindbergh made overtly pro-Nazi statements. I haven't researched this deeply, but nothing in this post shows outright Nazi sympathies, more a realistic appreciation of German capabilities. Had the Russians collapsed, as they appeared to be in the process of doing in September 1941, the U.S. and Britain would never have been able to mount an invasion of the Continent prior to 1950, at the earliest. I doubt we would have persisted that long.
BTW, the Wansee Conference took place in January 1942, shortly after Lindbergh spoke and after the U.S. had entered the War against Germany. And after German reversals outside of Moscow. One could argue that Lindbergh was prescient, that the Wansee conference was at least in part a reaction to the U.S. entry into the War, when it became apparent to Nazis that they might not win the thing.
