The Dollar and Interest Rates

I really don't see any alternative to the dollar out there. There's a dominant currency in the world. I have a feeling that everybody, anybody with brains out there in the world trust the Chinese central bank even less than the Federal Reserve. So why would you trust them? Saudi Arabia and other countries in the world will start diversifying the basket of currencies they have. And nobody cares about Saudi Arabia, UAE's currency. The dollar's importance will decline a little bit. But it's not like they trust the European central bank or they trust the Japanese central bank orthey trust the China central bank least of all probably.
