Second the US Dollar is under alot of pressure with its debt rising and more QE might be on the way - as Bernanke said in his Dovish statement 2 weeks ago about the "For-seeable Future" and the Dollar just went south in no time.
I dont really see the dollar recover after all the peril the USA has been in - Especially with the NSA and Snowden row and now that USA wants to arm the Syrian rebels - which will cost $1Billion a year - Detroit is in $18 Billion Debt and declared Bankruptcy - Pension funds are now all frozen to pay the government debt - So more QE is on the way and that is very bad for the dollar.
Essentially US Dollar is in serious trouble and recovery is very slim - US Dollar might decline very rapidly across the board agains all currencies. China's economy showing signs of recovery, Russia is rising and the US Dollar is weakening
The dollar might still be king but looking at the future where all the currencies were trading against dollar the tables of fortune are turning and the dollar is trying to trade against all other currencies to retain its value.
There is a saying: Quit while you are ahead or still can - But it does seem the US dollar is not getting the message.
