Throughout the ages, many countries and nations have been submerged in the long river of history because of wars and conflicts, and many powerful countries have stood out and left a strong mark, and Britain, as the birthplace of the first industrial revolution, is one of them.

Britain is an island nation whose strength was drastically reduced after World War II, and now, Britain's military strength is not even in the top three in the world. However, before this, Britain was the largest colonial empire in history, because it took the lead in completing the first industrial revolution, followed by rapid economic development and rapid productivity. At the height of British colonialism, all continents except Antarctica had British colonies, which provided Britain with raw materials and cheap labor, and most importantly became a dumping market for commodities, and Britain quickly accumulated primitive capital through overseas colonial expansion, and soon became a world hegemon.
The Russian Empire was a great power with world influence and the last monarchy in Russian history. At that time, Russia's land area reached 22.88 million square kilometers, and the population ranked third in the world. Because the Russian Empire was located in Europe, it also participated in the Napoleonic Campaign, but Russia unexpectedly interrupted Napoleon's record of consecutive victories, and the then Emperor Alexander I was regarded as "the savior of Europe". Russia also actively expanded into the Far East, even occupying Central Asia, and later became a country that could compete with Britain.
Compared with the above two countries, Germany does not have a very prominent advantage, but why does it dare to start two world wars? Before the First World War, Germany's national strength was limited, but it was ambitious and always wanted to compete for world hegemony, so it concentrated on developing the army strength, even so the country's military strength was still limited, and the First World War ended in Germany's defeat. But Germany did not die, 20 years later launched another world war, the German Fuehrer Hitler at that time was a war maniac, under his leadership, the German army swept through Europe, but because Hitler did not have a stable situation, and eager to go to war with the Soviet Union, encountered multinational attacks, and finally ended in failure.
Anyone who has studied this period of history knows that Germany launched two world wars in a short time, and the most crucial reason was people. The quality of the German army is very high, taking World War II as an example, the ratio of losses between the German army and the United States and the United Kingdom is 1:4, and the United States and Britain can be said to be one of the most well-equipped units at that time. Although such a country is restricted from developing its military, no country can let its guard down.
