It is an indisputable fact that in today's world, the United States is firmly on the throne of world hegemony with its powerful economic and military strength. Since the end of World War II, the United States has waged many wars around the world, whether in Vietnam, Iraq, or Afghanistan, and its military involvement has brought great suffering and losses to the peoples of the warring countries. As a result, in the eyes of some, the United States is seen as a "warmonger" who believes that as long as the United States loses its hegemony or falls, the world will be at peace. But can such a scenario really become a reality?
Military expert Zhang Zhaozhong gave his opinion on this issue. He believes that the fall of the United States does not mean peace in the world, but may trigger new turmoil and conflicts. If the United States, the gusher of the global order, withdraws from the stage of history, then countries that have expanded outward many times in history, such as Japan, may once again move towards expansion and war due to the peculiarities of geopolitics. Similarly, Germany, a country that has historically sought to unify Europe, can behave in the absence of external counterbalances.
Zhang's view is based on a deep understanding of historical and realpolitik forces. The United States does play the role of the world's policeman in many places, and its presence can in many cases counterbalance or even curb the expansionist impulse of some countries. U.S. hegemony does not come without a price, but to a certain extent, it also provides a relatively stable structure for the international community. If this structure collapses suddenly, the balance of power among the countries of the world will be disrupted and new destabilizing factors will emerge.
So what should we do if we can't simply expect peace from the fall of the United States? Zhang Zhaozhong and many other international relations experts believe that efforts should be made to promote the establishment of a more just and rational international order. In this order, common development and common prosperity of all countries on the basis of equality and mutual benefit is the correct way to achieve world peace. This means strengthening multilateralism and international cooperation to resolve conflicts through diplomatic means, rather than relying on unilateral action or force. 
When we look at the influence and position of the United States in the world, we can analyze it from different angles. Economically, the United States is one of the largest economies in the world, and its economic activities have a wide-ranging impact on global markets, ** and the financial system. U.S. technology innovation, multinational corporations, and financial institutions play a key role in the development of the global economy. Militarily, the United States is one of the most powerful military powers in the world, with advanced equipment, a powerful navy and air force, and military presences and bases around the world.
These military forces have an impact on international security and stability. In terms of international institutions and organizations, the United States is a permanent member of the United Nations Security Council and plays an important role in international organizations such as the World Organization (WTO), the International Monetary Fund (IMF), and the World Bank. The soft power of the United States, such as culture, technology, education, and **, also has a wide impact on the world, shaping the values and trends of the international community. However, the United States' international policies and behavior are often criticized, especially when it intervenes in the affairs of other countries. In the wars in Afghanistan and Iraq, U.S. actions led to prolonged instability and humanitarian crises that damaged its international image and fostered hostility toward the U.S. in some areas.
In today's globalized world, the sudden collapse of any country can bring instability to the world. The United States does have enormous influence, but it is also part of the global system and is closely connected to other countries and regions. Therefore, any suggestion that the world will be peaceful after the fall of the United States is too simplistic and ignores the complexities of international relations. On the contrary, true peace requires the joint efforts and wisdom of the international community. 
In conclusion, while the global role of the United States is often debated, its role in maintaining the international order cannot be ignored. Zhang Zhaozhong's view reminds us that world peace is not an automatic result of the collapse of one country, but the need to build a more balanced and just international system, resolve conflicts through cooperation and dialogue, and jointly promote global stability and prosperity.
