The Barbarossa Plan is perfect. What is its mistake?

Plan Barbarossa? It's perfect. What's wrong with it? One reason is that Germany has? Pig teammate? Italy. At that time, Germany and Japan, the two axis countries, were advancing on their respective battlefields. Italy, then known as the sixth military power in the world, was defeated by a small Greece. Therefore, Germany, as an ally, had to send troops to help good friends find places. Therefore, the Barbarossa plan was forced to be postponed for more than a month, which also led to the failure of the Germans to occupy Moscow before the arrival of the Russian cold current. Of course, this plan can't be completely allowed to fail? Pig teammate? The biggest mistake of this plan lies in Hitler's blind confidence in the German army. He didn't consider the combat effectiveness of the Soviet Union. What surprised him even more was that the Soviet Union would put all its resources into the war under a highly centralized and cohesive national system, and even find out the last grain for the war. Another important reason is that the disadvantage of Germany's lack of resources was exposed after being dragged into the war of consumption by the Soviet Union. After the war with the Soviet Union, the consumption of oil was huge. You know, the blitzkrieg in Germany is the superb cooperation of mechanized troops. If there is a shortage of oil, German tanks will instantly become scrap iron, and Germany's combat effectiveness will drop by at least half. Another big reason is that this plan is perfect, but it is a strategic failure. At that time, after tasting the sweetness of the Soviet Union, Germany did not continue to advance according to the established plan, but changed its plan. It should have taken Baku oil field to make strategic compensation for itself, but turned to Moscow, and after a long time turned to attack Baku, which laid the groundwork for Germany's failure in the future. Moreover, Germany underestimated the cold weather in the Soviet Union. At that time, most of the German soldiers were fighting alone in the snow, and the lack of anti-freezing design for German tanks and planes was even more difficult.
