Wrong, the Global debt is denominated in many currencies. The USD being the main one - not the Only one.
Yes, the US Fed can print money by pressing a few keys, but that will drive up inflation - as it has done for the last 4 years.
Further, major countries are de-dollarizing, which makes even harder to print more money or refinance existing debt, without paying higher interest rates.
The days when the US can print as much $$$$$$$$ out of thin air as they want, and expect the world to absorb it, are gone.
Watch the rise of gold prices and cryptocurrencies.
