It's actually VERY funny that some people in BitcoinTalk believe, or maybe they're merely saying it, that the time of the United States' role as the dominant super power "is over". But what is China doing? Because with their economic and military strength, they can't even invade Taiwan, nor can they stop the U.S. from attacking Venezuela and soon, Iran.
¯\_(ツ)_/¯
No, nobody is saying that American dominance has ended. They remain the number one superpower and will maintain that position for several more decades. However, we should not deny that this dominance is being challenged by the rise of China and BRICS. The USD still dominates globally, but is gradually losing market share as the idea of dedollarization become more widespread
I won't mention anyone's names, but there are people in BitcoinTalk who post that. It's laughable.
About China, and the BRICS - they could "challenge" the United States Dollar, BUT it's not currently a threat. If it starts becoming a threat, then I'll be the first to admit that. But RIGHT NOW, let's not spread bull-crap.
The world has changed, and use of military force and disregard for international law still help the US maintain its position. But in the long run, this only leads countries to seek way to reduce their dependence and look for alternatives.
The US is not the first and only superpower to dominate this world. They replaced the British Empire as the dominant world power after WW2. History has proven that no nation can maintain that forever. So, let's wait and see how long they can maintain that.
How many years, in your opinion, does the United States left as a "Dominant Super Power"?
