Japan bore little resemblance to Nazi Germany. Trade with Japan was still robust until FDR started trying to provoke Japan with sanctions and propaganda.1) The USA also had trade & diplomatic relations with Nazi Germany during the 1930s. With regard to both Japan and Germany the trade started to fizzle out by late 1930s.
In Japan's case, the brutality of their attacks against China (Nationalist)* caused increasing displeasure in the USA, Especially after the 1937 'Rape of Nanking' episode.
You didn't read any of the sources I recommended, did you? No, you didn't. You just got on here and repeated the traditional version of events.
How about the brutality of China's attacks on Japanese forces and on each other? How about those actions? FDR didn't care one whiff about Chinese brutality and atrocities, just as he didn't care about Soviet brutality and atrocities.
And why were the Japanese even attacking Nanking, huh? Do you know? Which side shunned negotiations and attacked the other before that? Do you know. Here's a hint: the first letter of the side that started the fighting that led to the assault on Nanking starts with a capital "C."
I'm not going to bother with the rest of your recitation of the traditional pro-FDR/anti-Japanese talking points.
You should read Appendix C in my book The Real Infamy of Pearl Harbor (not Appendix B, as I mistakenly said earlier). It's 60 pages long and is titled "Getting Some Facts Straight About Imperial Japan."
