The US Dollar Is the Global Reserve Currency

Most countries around the world that have massive current account deficits and import more than the export, their currencies are devalued against the other currencies like the dollar. The reason that doesn't happen to the United States is because the US dollar is the global reserve currency. Any country that tried to challenge the dictatorship of the US dollar was targeted by regime change in war by the United States. But now the situation is different. In Eurasia, there are two powers, China and Russia challenging US hegemony and their allies. They're challenging US hegemony militarily, politically and economically.
