That's why they killed 20 million chinese? That's why they experimented on Chinese and koreans and vivisected them? That's why they raped Nanking? Because FDR made them look for oil?
Don’t think you have caught the point.
The oil embargo was to stop their conquering of China.
Much like the US in the 1970s, a decision was made that no embargo of oil was going to dictate national policy, so they did not stop their empire building, but instead sought additional oil.
It’s fun to think religion or morality or whatever decides wars since 1900 or so, but it’s oil. Pretty much it’s always oil. View things thru a prism of oil and you’ll understand.
