This is obviously wrong. The US dollar will quickly depreciate in the next 1-2 years. Americans should not be so selfish. Now it is a peaceful era. There is no need to control the global economy. It should be fairer and more free.
Well I think that USD is very strong because it has high demand and it can only get broken if all the countries reduce demand for USD and not just China or Iran. So the fact that whether dollar will depreciate or not depends on the US policies.
