When did the United States close down?

well, I think the United States will go bankrupt when the goods in the United States can't be sold, and then the American banks won't lend them money.

hehe, a joke.

this is an anthropomorphic statement. My anthropomorphic answer is:

When the ideology of the United States can't be accepted and can't be sold, the American economy is on the verge of collapse under the strong impact of the economic forces of China, Japan and Europe. At the same time, due to the loss of confidence in the future of the United States, other countries in the world will no longer pay for American consumption, and the United States will close down like a poorly managed enterprise-collapse. The current consumption of the United States mainly depends on foreign money. For example, Japan is the largest creditor of the United States, and China also holds hundreds of billions of dollars in claims of the United States. The life of Americans now is vividly called "borrowing other people's money to live", so once the United States is considered unsafe and unreliable, the end of the United States will come. This is the fundamental reason why Americans are crazy about strengthening their military strength and attacking the military strength of other countries! )
