It's just a group of scum who are worse than animals, without any animality, and all of them have rolled into the garbage dump of history.
Germany's failure mainly lies in three aspects:
1, strategic two-line operation. I won't say much about what everyone knows.
2. Hitler's Nazi crimes against humanity led to injustice and lack of help.
3. Allies are far apart in appearance, not only do not cooperate, but also create troubles for each other, dragging their feet militarily, politically, in terms of resources and time.
Yes, they were indeed tactical giants at that time, but they lacked in strategy. The conspiracy and moral reaction to wage war directly led to people's abandonment, and they were at a disadvantage in manpower, intelligence, production and resources, so failure was inevitable.
However, we should still learn from our lessons, learn from each other's strong points, and build an army like the German Defence Force-with the potential of tigers and wolves, high chivalry/quality, excellent equipment/tenacious fighting, firm belief, and our military strategic thinking, correct command and brilliant tactics, it must be an invincible army on this planet.
