The change of dominant states is not uncommon in modern history. Over the past few centuries, the palm of the world championship has repeatedly passed from one leader to another.
History of the Last Superpowers
In the 19th century, the undisputed world leader was the "mistress of the seas" Britain. But from the beginning of the 20th century, the role of the first violin passed to the United States. After World War II, the world became bipolar, when the Soviet Union was able to become a serious military and political counterweight to the United States.
With the collapse of the USSR, the USA again took on the role of the dominant state for a while. But the sole leaders of the States did not last long. By the beginning of the 21st century, the European Union was able to become a full-fledged economic and political union, equivalent, and in many ways surpassing the potential of the United States.
Potential World Leaders
But other shadow leaders did not lose time during this period. Over the past 20-30 years, Japan, which has the third state budget in the world, has strengthened its potential. Having begun the fight against corruption and accelerated the process of modernization of the military complex, Russia is claiming to return to the leading position in the world in the next 50 years. Brazil and India, with their colossal human resources, can also in the near future threaten the role of world superpowers. You should not discount Arab countries, which in recent years have not only enriched themselves with oil, but also skillfully invest their money in the development of their countries.
Another potential leader that is often forgotten to be mentioned is Turkey. This country already has experience of world domination, when the Ottoman Empire ruled for almost half the world for several centuries. Now the Turks are competently investing both in new technologies and the economic development of their country, and are actively developing the military-industrial complex.
