@izzythepush,
What happens in the external world will not save the United States currency. A 39 trillion-dollar debt is a tremendous amount of debt. The service on the debt is already robbing millions of health insurance. You can't spend a dollar twice, but you can borrow unlimited dollars with no chance of ever paying them back.
If the dollar becomes worthless it is worthless to everybody already the interest on the debt is cost more than defense and Medicare. That is not the debt just the interest payment on the debt.
The United States days as a superpower are now numbered and China will be the next superpower. The world superpowers have always moved westward since Holland was the world superpower. As soon as a world superpower attacks and destroys its middle class it is like cancer it is only a matter of time.
China has already won the game it is just a matter of when it decides to collect its winning.
China is in it for the long game they will learn from the United States' mistakes. They will wait and play from a position of power.
I will agree that the Iran war was a huge mistake. Little Hitler thought that war was like a real estate deal.
