Since the Japanese began to invade China, their economy has been very depressed, so they have thought of replenishing them with supplies from other countries. But in the end the United States terminated not only the supply of their oil, but also the delivery of their military supplies. Japan was at an impasse, and they had no choice but to withdraw from Japan and declare war on the United States.
At the beginning, when the United States did not join the Second World War, in fact, Hitler was very worried, he knew that Roosevelt could not always maintain a neutral attitude, so he expected in his heart, expecting that Japan would never find trouble with the United States, so that he could relax his heart to confront the Soviet Union, if Japan helped him at this time, then sooner or later the Soviet Union would be his "pocket." But what he did not expect was that the Japanese actually bombed Pearl Harbor. ”
Then the Japanese bombing bombing, even left a way back for the United States. The reason is that at that time, the Japanese only bombed Pearl Harbor, but forgot about the huge oil depot in the United States, which contained 4.5 million tons of oil, and there was no loss of this oil at all. You know, "cutting the grass to remove the roots", but now the "roots" are left to the United States, their so powerful logistics support department, you bombed his fleet and airfields, although to a certain extent the United States has lost a lot, but his "roots" are still there, this bombing has not blown up to its roots. So, when Hitler learned of this, he directly scolded Japan as a "pig teammate."
Originally, they still expected Japan to help them at a critical time, but they did not expect that they would not be able to count on it, but they would also add trouble, originally they had to rely on the United States to have 30% of their oil, although the share of 30% of them was not very large, but if these 30% were missing, then they could only rely on the oil fields on the European side to obtain oil. So did Hitler curse Japan?
