The correct answer is - oil.
The Japanese Empire, under the rule of Emperor Hirohito, in order to manage to continue with the expansion and gain new territories, needed much more oil than what its supplies where.
The need for oil meant that Japan will attack the places in the region where there are solid amounts of oil reserves, and they did. They attacked and conquered parts of Southeast Asia, and got hold onto the large oil reserves that they desperately needed for their military machinery.
Answer:
it says on a website "he denounced the attack and asked congress for a declaration of war on Japan"
This is a question asking a personal opinion, so I'll give you mine.
I believe the literature from this period influenced the future generations of American Literature is it taught us to be independent, to stand up against those who simply expect us to follow like mindless sheep. It influenced literature by showing everyone that their opinion matters, even against your authority, and that has influenced books and passages heavily since.
Traces of these themes can be seen everywhere. Authors from all over make books about how standing up is the best thing to do, and how being independent is important. Books, passages, texts, websites, etc all preach this. This is presented in various situations where independence is important.
