The two sides used hundreds of thousands of elite troops and advanced military equipment to carry out fierce confrontation for more than four months in the wasteland with overgrown weeds and undulating sand dunes. Japan suffered the worst defeat for the first time since the Russo-Japanese War because of its backward military ideology and tactical technology.
After the failure of "going north", the dream of attacking the Soviet Union and occupying Siberia was shattered, so we turned around and planned to "go south" to seize more war resources (oil) in order to annex the world's reserve successor resources in the future.
Nanyang was colonized by Britain, the Netherlands and the United States, which added difficulties to Japan's plan to go south. At the same time, because Japan and the United States pursue completely opposite East Asia policies, Japan and the United States will inevitably have a collision of interests in East Asia.
1940 The theory of southward advance in spring and summer rose twice in Japan. It took half a year from the first upsurge of 1940' s theory of southward advance in spring and summer to the outbreak of the Pacific War at the end of 194 1.
Japan has been slow to go to war with the United States, and the scheduled time for going south has been cancelled or postponed many times. The main reason is that the Japanese people's anti-Japanese struggle disrupted the Japanese invasion and deployment, forcing Japanese fascists to postpone their southward journey many times. Coupled with the shortage of oil, I took risks and bombed Pearl Harbor.
Japan began to expand to Southeast Asia at 194 1, which aroused the dissatisfaction of the big countries in this region. In order to give the Japanese a warning, the United States froze its trade with Japan, among which high-octane oil was the most important. Without oil, Japan's war machine can't run, and the ship is broken, which means that it can't continue to invade. In order to ensure the normal invasion and plunder of oil, the Japanese army decided to take a risk.

Before the Pacific War broke out, China and Britain had realized the importance of Myanmar's strategic position and the possibility of being attacked by Japan, and began to plan a joint defense plan. 194 165438 On February 23rd, China and Britain signed the Sino-British Agreement on Joint Defence of the Burma Road.
However, at the beginning of the Pacific War, Britain refused to allow China's troops to be deployed in Myanmar on the grounds that a formal alliance between China and Britain was sufficient to ensure Myanmar's security. It was not until February 1942 that Britain realized that it could not guarantee the security of Myanmar and asked China to send troops to fight in Myanmar.
In the face of Japan's aggressive situation, the United States and Britain have taken corresponding economic sanctions against Japan. 1On July 26th, 940, the United States announced that it would impose measures such as "moral embargo", "export license" and "economic embargo" on Japan, and after Japan entered zhina, India, it would implement a scrap export license system for Japan. Britain also reopened the Burma Road on June 26th18th, and began to deliver aid to China.
194 1 On July 28th, 2008, the United States and Britain frozen Japanese capital in the United States and Britain, which was "the first boycott measure taken by the two countries against Japanese aggression since Japan began its aggression and expansion in 193 1 2008, and the first coordinated action taken by the two countries". However, judging from these sanctions, the United States and Britain are still unwilling to excessively stimulate Japan, especially not to impose an oil embargo.
On July 26th,1940 ~194115, the United States signed an oil export license for 7 million barrels to Japan, of which 3 million barrels have been imported to Japan, accounting for 1936~ 1939. It was not until August 194 1 that the United States announced an oil embargo on Japan. In September, the United States and Britain stopped all trade with Japan.
