They might also switch to the Chinese Yuan, especially if the trend of the last 20 years continues, and there's little reason to expect it won't imho.

Seeing as bringing CNY out of China is illegal, it would be really difficult for a country to import enough of it to run their economy. Whereas the most printed dollar bill is the $100, and 67 percent of them are outside of the US.

You may have noticed that sometimes things change over time, American financial dominance is likely to undergo some serious changes in the next decade as people begin to wake up to the new economic realities of the world.

Yes, and as America's economic power (and unity) wanes, it is losing its ability to sustain its freakishly powerful military, while China's meteoric rise makes them a very attractive new primary strategic partner. There's certainly all sorts of behind the scenes "influence" the US can still apply to traditional "allies", but the reason they've been able to do this so successfully is because of their economic dominance, which is disappearing relatively rapidly.
