During World War II, when Germany had not yet achieved a complete result in the contest with Britain and France, it quickly turned its guns around and engaged the Soviet Union, which had previously had a peace agreement. Many people have expressed their incomprehension, first of all, there are many people in the Soviet Union, and their strength is not weak, so why does Germany have to fight with the Soviet Union and not occupy the Middle East region with a lot of oil? In fact, in order to answer this doubt, we must first know two points, one is that the Soviet-German war is already indispensable, and the other is that the Middle East region is not as simple as we think.
First of all, Sud, although he signed an agreement in the early years, there is a good saying that there are no eternal friends in this world, only eternal interests. What's more, Sud was never a friend, at best a partner, and the agreement signed that year was only convenient for the two countries to share the booty. The leaders of both countries actually know that sooner or later there will be a war between the Soviet Union and Germany, but it is only a matter of time. Germany wanted to eat the Big Pie of the Soviet Union in one go, and the Soviets didn't expect Germany to turn the other cheek so quickly. Germany's fight against the Soviet Union was actually premeditated, and it was calculated that the Soviet Union would not have thought that Germany would send troops so quickly, and if it was caught off guard, the results would certainly be very gratifying.
Moreover, in Hitler's eyes, the Soviet Union was not a powerful enemy, after all, it had been beaten by tens of thousands of Finns and lost its armor. Germany, on the other hand, could have won the Soviet Union directly by relying on a victorious blitzkrieg. Moreover, Hitler's dream was to dominate the whole world, and naturally he would not let a big country wait to pick up the bargain at any time, so it was better to get rid of them as soon as possible. Of course, the above is only a preliminary plan of Germany, and there is still a reason why it is necessary to send troops to implement it, that is, the problem of German supplies. Germany had already experienced several wars and supplies were running out, and the Soviet Union had abundant resources, which were naturally looked at by Germany.
The reason why we do not fight in the Middle East is mainly because of the problem of resources. At present, the Middle East is the world's main oil producer, but at that time, the Middle East had just begun to develop oil, and as for the size of the reserves, people at that time did not have a definite conclusion. But in contrast, the Soviet Union has successfully owned the high-yield oil in the Caucasus region, and Germany naturally will not run to fight a reliable Middle East. Moreover, most of the Middle East at that time was still in the hands of the Americans, and although Germany was known as a great power, the situation at that time did not allow him to provoke the United States.
Germany's invincibility in Europe was largely due to the rapid advance of its mechanized forces. However, the terrain of the Middle East was complex and it was not suitable for German combat. And Germany's navy is very weak, once it chooses to fight in the Middle East, it may be suppressed by many parties, and Hitler's dream of world hegemony may have just emerged and been destroyed in the bud.
