Why do we always ask the US to rein in the situation? Wouldn't it be better to let the US fall off the cliff? !

This is because Chinese culture generally does not curse people for falling off a cliff, and falling off a cliff is just a saying. As the saying goes, saving a person's life is better than building a seven-level pagoda. Culture determines this. The United States is the only superpower in the world. It has a government, a House of Representatives, and a Senate. Their respective rights form mutual constraints. If one party wants the United States to fall off a cliff, the other two parties will definitely stop it. It would be difficult for such a thing to happen in the United States, at least. America is not stupid. This statement is mainly caused by the cultural differences between China and the United States.
