How did Roosevelt respond to German aggression toward Britain differ from his response to Japanese aggression toward China?

Roosevelt's response to German aggression toward Britain was characterized by a greater willingness to provide support, as seen through measures like the Lend-Lease Act, which allowed the U.S. to supply military aid to Britain even before formally entering World War II. In contrast, his response to Japanese aggression toward China was more cautious, focusing on diplomatic pressure and economic sanctions rather than direct military involvement, reflecting a reluctance to engage in another conflict following World War I. This difference stemmed from Roosevelt's assessment of the European threat as more immediate and pressing compared to the situation in Asia at that time.
