The United States is in a world-class position in every respect, and the rise of the United States actually began after World War II. I'd like to illustrate this with what the Chinese often refer to as the right place, the right time, and the right people.
Timing: the post-World War II peace, the development of the environment, as well as Europe suffered from war, Asia has just become independent, the United States undoubtedly has the healthiest body, but this time is the other big countries generally have a lot of domestic problems at the time. Therefore, the rise of the United States in the post-World War II period is quite understandable.
Location: the United States has fewer neighbors, a long coastline, farther from the main continent of the advantages of the United States, embodied in World War II, was not disturbed by the fire of war, but can be left alone, into the attack, retreat can be defended.
People and: the United States since Washington, is a country established by the elite, to be precise, lawyers, and thus at the outset, the U.S. system is perfect, and do not have to be subjected to some of the historical legacy of the constraints, it can be very easy to cut off the adverse effects of the tradition, and chose to inherit the best parts of European culture.
It can be said that every president of the United States and his team are absolutely first-class talents in governing the country, and the precision of the operation of the entire American state apparatus is attributed to their perfect system design. Now any country in the world in this point are not as good as the United States. Similarly, it is precisely because of this inimitability that the United States quickly seized world leadership after World War II. While others were still struggling internally and externally, America's domestic system was already perfect.
After finishing these three points, I would like to jump the perspective to another key point: currency
As we all know, the United States led the establishment of the Bretton Woods system after World War II. There is no doubt that this is the most and most powerful tool for the United States to gain the leadership of the world economy. And the United States is not without shortcomings, to the later collapse of the forest system, the United States in order to maintain this absolute leadership, began to set up the dollar - oil currency system, at this time, the United States is equal to the closest relationship with the economy of the most closely to the oil to the hand. And in the eighties, Japan's economic power to the United States of America's erosion, so that the United States is very annoyed, in a variety of means, Japan was forced to sign the Plaza Agreement, and since then the collapse. And the EU integration process, too, has taken an extremely long road due to the repeated obstruction of the US, which even staged the Kosovo war to sabotage the process.
The only advantage of the United States is the currency. The emergence of the euro is a huge challenge to the dollar, if you look closely, you will find that the euro everywhere by the U.S. suppression, and even once on the verge of death. The Soviet Union, to a large extent, just did not see the impact of the currency on the world economy, did not realize the changes in the integration of the world economy.
And the United States is now declining in all aspects of strength compared to the previous, absolute strength, relative strength have declined, and thus there is also China to reform the currency of the argument, and also a call. Visible, the dollar's currency status is the target, but also can be reflected from the side, the United States in the world dominant position, to a large extent from this monetary system. And this monetary system is also the United States of America's most most core interests, once lost, the United States is no longer the world hegemony.
If you care to check, when Zhou Xiaochuan proposed to change the currency, the United States Treasury Secretary Geithner began to pay no attention to, said "can discuss this issue", followed by the dollar's wildly falling, so he said, "the dollar is now the best choice, there is no need to reform! He then said, "The dollar is the best choice now, there is no need to reform", and only then did the fall stop. Through this change, we can see that the dollar is still relatively fragile. And before the news that OPEC is ready to conduct oil transactions with non-US countries, without the dollar settlement, the news came out, the dollar is wildly down, until OPEC said, we did not say such a thing. But he said he did not say, does not mean not prepared to do so, the relevant European, Chinese and Russian, and even India and Japan are beneficiaries, these countries on this matter "smile but not say".
If you want to ask, why not reform the dollar now, the reason is very simple, there is no suitable program, there is no suitable time. The game of politics is a long and arduous process.
Figure out the monetary status of the dollar, and it's easy to understand where American supremacy comes from. All the advantages come from money, more money, good development, more talent, and then a virtuous cycle, and vice versa is a vicious circle, worse and worse. Without the half-century-long monetary dominance of the US dollar, it is impossible for the US to dominate the world. Of course, as mentioned, the US system is its strongest guarantee to seize these opportunities.
Finally, to make a bold prediction, along with the diversification and multipolarity of the international political landscape, the dominant position of the United States will become weaker and weaker, and finally disappear. Of course, this process is very long, as with its rise, it may take another half a century, day in the middle of the shift ah.
