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

Roosevelt's response to German aggression towards Britain was primarily characterized by diplomatic support and material aid, exemplified by measures like the Lend-Lease Act, which aimed to bolster Britain's defenses against Nazi Germany. In contrast, his response to Japanese aggression towards China was more cautious, as he faced significant domestic isolationism and was constrained by the need to maintain neutrality while balancing international relations. While he condemned Japanese actions and provided some support to China, it was more limited and less direct than the support given to Britain. Ultimately, Roosevelt's responses were shaped by the geopolitical context and the urgency of threats posed by each aggressor.
