I am German and a major history buff. My grandfather fought in the Wehrmacht and just listening to his old stories back when I was a kid made it kind of obvious why Germany collapsed. Hitler simply bit off more than he could chew! He famously said  that the Soviet Union was weak, and if you kick in the door the entire rotten structure would come crashing down.
Then, a few months later, the idiot declared war on the US. Now he is dealing with an enemy that outproduced the axis and the other allies combined! Germany was choosing between weapons and food while the Americans have plenty of both, they would supply their allies and still have a huge surplus.
Germany’s loss of equipment and experience soldiers were irreplaceable while the Americans had theirs replaced in a week and then some.
The Soviets had millions of men to throw millions of men into the meat grinder, as you can see in the current Ukraine conflict. Russia doesn’t put the same value on their citizens than we do.
Opa was taking prisoner by the Americans in France, he said they fed him better as a POW than what Germany was feeding its officers, let alone a foot soldier like him.
America paid in material and food and Russia paid in blood. Fun fact the US is the only nation to profit from World War II.

Good video !

What do you think was the single biggest mistake that led to Nazi Germany’s collapse?

Was it the decision to invade the Soviet Union, declaring war on the United States, or something else?

👇 Let me know your answer — I’d love to hear different perspectives.

"Why Nazi Germany collapsed so fast" ERM, it took the Germans six weeks to conquer France. It took the Allies six months to conquer it back.
It took the Germans four months to reach the gates of Moscow. It took the Soviets fourty months to drive them back to the border.

Invading Russia. No chance of winning, Russia had twice the population and 25 times the size of Germany. Germany had no business trying to invade Russia. And the assumption that capturing Moscow would have lead to a Russian surrender was foolish.

While the invasion of Normandy surprised the German army, the destruction of the Army Group Centre by the Soviet army uprooted what was left of the German ability to operate strategically. From that point onward, the Germans weren't just retreating, they were loosing their foothold, were chased out of the USSR and hunted down all the way back to Berlin, all while the Western allies were closing in and bombing Germany's industrial and arms production into rubble.

It didnt collapse suddenly. The generals knew for sure all was lost by 1944.

Underestimation of Barbarossa.

Never go to war with Russia. Germany forgot the wisdom of Bismark and paid the price. Same as what’s happening to NATO with their Ukraine project. Don’t poke the Russian bear.

Because they were fighting against the majority of the world perhaps

The Nazi economy was based on looting other countries, and could only grow by stripping other countries of their resources. In other words, a violent Kleptocracy. It could never last.

Operation Uranus

The Axis made the same  mistake.

Axis arrogance:

Germany and her axis partners including Italy attacked the USSR.

And

Committed atrocities.

Japan did the same against a divided China (Nationalists and Communists).

The Axis atrocities made the USSR and China fight back with great determination.

This enabled the US and Great Britain to be successful in Europe in the Pacific and Asia.

Germany and Russia invaded Poland,,,

Because they had no atomic weapons 😂

Short answer:USSR

Attacking Russia

General Patton: "We defeated the WRONG enemy." WW2

Donald Trump exhibits many of the same characteristics. He is also a mad man bent on destruction.
