The main reason for entering World War II is that the United States wants to redefine world interests. The United States is already in an economic crisis and depression. Although there was Roosevelt's New Deal, it still didn't get rid of it completely! In addition, the United States was the largest creditor of European countries at that time and joined World War II for economic benefits! It is a conspiracy to impose an oil, rubber and steel embargo on Japan.

Because the United States was anti-war, the embargo was a heavy blow to Japan. This is a chicken, and the raw egg is a sneak attack on Pearl Harbor. Now we all know that Pearl Harbor is also a conspiracy, a political conspiracy, so the United States has an excuse to go to war.

It was through two world wars that the United States established its position as the world hegemon!

As for the relationship between the embargo and China, it is just too superficial to be analyzed in depth. China is only a point of American world interests, and European countries are its biggest debtors! It is suggested to discuss from the economic and political aspects! This paper makes an in-depth analysis from the perspective of American balance of payments, creditor's rights and debts and post-war interest division.
