The reason why the Japanese army chose to take the initiative to go to war against the US army was mostly "forced by life".
First of all, from the perspective of resources, why Japan wants to launch a war of aggression, mainly in order to plunder more resources and develop its own economy, Japan is originally a small country with resources, coupled with its own strong military foundation, embarking on foreign expansion has become an inevitable trend. Only war can achieve the goal of feeding war with war, and oil is naturally needed to start a war. Otherwise, how can Japan's aircraft carriers, tanks, aircraft and other things work?
Although Japan occupied the three northeastern provinces, and these places were later rich in oil fields, unfortunately Japan did not find it that year, although a special expedition was set up to search everywhere, and also invited American experts to help, but unfortunately due to insufficient professional knowledge and insufficient equipment, the oil wells in these places have never been surveyed.
For example, the Liaohe Oilfield, which can only be surveyed at a depth of six kilometers, can only be explored by Japanese oil rigs. This is the problem of their own machine, but the oil fields in the northeast are not all deep and shallow, such as the Daqing oil field is only more than a thousand meters deep, this time it is a human problem.
At that time, japan's oil industry believed that oil fields would only appear where the oceans once existed, because oil was mainly evolved from marine life through high temperatures, so this theory was very popular in Japan at that time. Daqing did not conform to this doctrine, even if the plane had already found oil over it, the Japanese did not continue to search patiently in Daqing, because of the doctrine, they hastily concluded that there was no need to extract oil in such a place.
Japan didn't find the oil they needed in China, so naturally they looked overseas. Where overseas oil fields can be obtained, they are concentrated in the Soviet Union and Southeast Asia. Japan first tried to fight with the Soviet Union at Nomonkan, and after finding that it could not be done, the Japanese army shifted its aggressive vision to Southeast Asia. And these places are the territory of the United States, Britain and France, and the desire to extract oil in this place is undoubtedly a tiger's tooth and a tooth, touching the interests of the old colonists.
Japan's oil suppliers at that time were Britain, the United States, and the Netherlands, which controlled the lifeblood of Japan's oil, and with Japan's eager posture, and the Chinese representatives continued to complain to Roosevelt about Japan's atrocities. Eventually, driven by interests, the United States passed legislation restricting oil supplies to the Japanese army, a practice that led countries to follow suit.
If Japan does not choose to break this impasse as soon as possible, its existing oil reserves will only be enough to sustain military demand for half a year. Now as long as the US Pacific Fleet is solved, then Japan can gain the dominance of the Pacific for about half a year, as long as in this time period, the Japanese army's crazy attack will force the United States to the negotiating table.
So Pearl Harbor broke out.
And Japan is not desperate for the United States, after all, many Japanese high-level students are returning from the United States, they clearly know the monster-level military strength of the US military, but the bow on the string, has to be sent, mainly in order to be able to obtain southeast Asian resources.
The reason for this choice was that the Japanese army believed that the American masses, who had experienced the turmoil of World War I, were more willing to remain neutral, and that if war broke out, they might parade through the streets to form the greatest resistance in the United States. After all, the United States has always had a glorious tradition of isolation, and the people's willingness to participate in the war is generally not high, and they cannot afford the suffering and sacrifice brought about by the war, unlike the Japanese people who just happened to be reversed.
Japan's war with the United States was a big gamble, and due to the miscalculation of the situation, Japan finally lost to the active willingness of the American people to participate in the war.
