What is history: it is the echo of the past to the future, the reflection of the future on the past. - Hugo
Germans of German descent have always had the ambition to dominate the world, and the second world war is actually inseparable from Germany' push. Without Hitler, there might have been others who might have rushed out and stirred up the world.

From Germany's geographical location, even without World War I and World War II, Germany could not have become the world's first superpower.
It was precisely because of the doctrine of the world island and the heartland that Germany was able to launch world wars one after another. On this Asian, African and European world island, Russia is the heart of the world island, connected from the Atlantic Ocean to the Pacific Ocean, spanning more than 5,000 kilometers. Top-down can suppress Asia, the Middle East, and Europe.
Germany's geographical location is only in Western Europe, and even Britain's seizure of the Atlantic ocean strategic passage is more than enough and insufficient.
A rising Germany was suppressed by Russia's condescending positions while having no advantage in the competition for strategic access to the Atlantic ocean. The best way, then, is to first unify Western Europe, then absorb Central, Northern and Southern Europe, and finally seize the Atlantic Passage on the one hand, and on the other hand, engage in a life-and-death duel with Russia in Eastern Europe. This is the real reason why Germany launched the Second World War.
If Germany does not start a world war, it will only become a great power, and it will be a great power squeezed between Britain and Russia. But if the situation can be opened in World War II, then it is possible to become the world's largest superpower. This is Hitler's wolf ambition!
