United States:

It is the most powerful country in the world. However, the truth that "prosperity will decline" has remained unchanged throughout the ages. Without the support of moral power, if there is strong military power, the stronger the military power, the faster it will perish. I hope that the United States, which likes to be a "world policeman", can learn from its own history and stop launching unjust wars that cost countless lives like the Korean War or the Vietnam War.
