Is the US economy finished?

Disclaimer
-----------------------------------------------
I asked myself: when the Soviet Union collapsed, would the United States have been okay?
Even though the US is the provider of the reserve currency... the $40 trillion government debt has become a painful reality. Market participants can no longer criticize the debt of smaller nations, because the US is the standard.
We can no longer demand that countries with debts under $40 trillion liquidate or declare bankruptcy.
The logic that "the US doesn't have to declare bankruptcy because it has strong military power, while small nations must" has fallen apart.
When the US economy is normal, it emphasizes free trade... and tries to eliminate the tariff barriers of other countries. However, conversely, when the US economy faces a crisis, it attempts to defend itself through protectionism or by imposing tariffs.
President Trump is transparent. He is putting into practice the fact that the US is in trouble through tariff bombs. Usually, whether a great power or a small nation, they do not reveal their weaknesses... seeing how Trump reveals them directly, he is indeed a transparent person.
