In other words, since the formation of mankind, war has always accompanied the advance of human civilization. War is cruel and merciless, and it is also the nature of war to eat the weak.
In the 1930s and 1940s, the outbreak of The Second World War, during the Second World War, the Germans supported their growing ambitions with their own "black technology" and extremely strong industrial production capacity, and the "lightning tactics" made countless people in other countries lose their precious lives, and countless families became broken.
Of course, after the end of world war II, for Germany, which chose unconditional surrender, they also made a deep confession for their crazy behavior.

The Germans won the opportunity to apologize and reflect deeply because they finally chose to admit defeat and "thank" the defeat, otherwise Germany would become a wild horse that was out of control and fearless of death, and their future would be endless darkness.
So, do you know what an important "hardware" condition that led to the defeat of Nazi Germany was? It is a quiet and compact part – a bearing.
Yes, he is an industrial bearing, in everyone's common consciousness, the "bearing" thing should not be counted as an industrial part of the weapon at all, but in the Second World War, an inconspicuous "bearing" became the last straw that led to the defeat of Germany.
At first glance, it seems incredible that a small bearing could cause Germany, which was once very strong, to collapse rapidly. Small bearings are so unpretentious that most people do not touch industry in their daily lives, but they will often encounter objects with bearings.
But it is such a very ordinary thing, which has an irreplaceable and important role in some fields, especially in industrial machinery and other aspects, all kinds of german vehicles during World War II, all equipped with many large and small bearings of various specifications.
By 1942, the world anti-fascist camp was formed, and 26 countries jointly formed allies to begin to counterattack the Axis camp with Germany, Italy, Japan and other countries as the core.
In the European theater of 1943, the Allied camp changed from passive defense to active attack, and it was really difficult to fight in the counter-offensive stage, and the United States began to mobilize a large number of fighters to bomb various substantive German targets but the effect was not significant, but the self-inflicted losses of the American army were increasing.
There is such a sentence in the Chinese art of war: cut off the enemy's grain and grass to make the enemy surrender, and the US army wants to use this trick to deal with the German army, so it sends fighters to bomb the German logistics arsenal and material bureau, etc., but the results are still very small.
Later, the US intelligence agencies found that if they could cut off the production area of one part of the German armored fighting vehicles necessary for the production, could it have a miraculous effect? Therefore, the US military aimed the target at the "bearing".
During World War II, the use of bearings in German tank fighters was very large, and if the German military industry lost the supply of bearings, then the combat effectiveness of the German army would be greatly reduced. After the Americans discovered this deadly part for Germany, they immediately began to investigate the supply chain of German bearings.
They were pleasantly surprised by the results of the survey, as Germany's industrial distribution and bearing production were concentrated, and almost all of the German production bases for the German army were established in a small city called Schweinfurt, where the bearing factories almost monopolized the bearing supply chain in Germany.
Later, U.S. intelligence agencies again conducted various investigations into the German production base and found that the small city of Schweinfurt did not have any air defense facilities.
In other words, the Germans themselves did not realize the importance of this small bearing to the development of the whole war. Subsequently, the Americans began to carry out indiscriminate carpet bombing of this "bearing town" in Germany.
Faced with countless heavy explosives, the town soon became a ruin, and after suffering a devastating blow, the German army, once known as the mechanized lightning force, was like a winged war eagle, and then even "fell" to the point of needing mules and horses to tow the chariot, so that the German army fell into a very passive situation.
The german army was no longer able to compete with the Allies, and after more than a year of hammering, Nazi Germany announced its unconditional surrender on May 8, 1945, and the European theater of World War II officially came to an end.
