Well it seems like that dollar is the king but eventually mostly anti american governments who have there own agendas rather than giving strength to dollar, are holding large amounts of US dollars, in specific reference China, Russia, Brazil, germany and euro zone.These large reserves if manipulated can trigger a financial crunch much bigger than expected, or any one can anticipate right now. US must take out there dependency on foreign reserves and using it as an instrument of dollar strength.

The change to euro is imminent not just because of economic analysis but various geo strategic analysis as well.

Americas economic submission to china is a example in consideration, US economy is dependent largely on China, which could use it in there favour in case of some geo strategic disputes which may arise because of US involvement in ASIA.
REGARDS.
