Everyone has to understand.  The US-NRE's Banksters fired the first shot for this atrocious  behavior by massively abusing the "dollar's" reserve status since the 1945 Bretton Woods agreement.  They did even more damage by going off the gold standard in 1973 while establishing the Petro-Dollar system. They made thing even worse by selling tens of trillions of dollars to the world in bogus, worthless, MBS, CDS, and other pieces of fictitious financial  toilet paper starting in 2001, and finally during the subsequent collapse of their paper Ponzi scheme in 2008, they went financially insane and flooded the world with tens of trillions in open and stealth "quantitative easing". 

All designed to pump up their ENTIRE financial complex to be used for high yield, high risk (not to them of course), low value targets world wide, attacks against those countries currency and bond markets who refused to participate in the "Washington Consensus" and the Banksters' Ponzi schemes , all the while continuing to fund their Empire splurge to further the AIPAC/Israeli PNAC Protocols. 

Japan, and all the other countries out there are simply inflating to counter this financial aggression. - mpg

Currency Wars - Def.  Commonly interpreted as printing (Quantitative Easing) until a nation's currency is devalued relative to others in order to protect its manufacturing base and help its export industry. --  However such wars are very unequal or fought for a variety of very different reasons. Some countries Banksters have powerful geo-political or financial relationships that can force others to take their currency.  While others, can use their military and/or their Shock & Awe tactics to violently put other countries deeply into interest bearing debt to be paid back in the Banksters' own currency.  Making the Banksters even wealthier. -- Also, in a few rare cases, perhaps only one (so far), some Banksters are powerful enough to use their massive QE programs in an attempt to artificially Leverage their entire financial complex to be used for further economic warfare or monetary advantage.  Whatever the case, it is an axiom that...."whoever can print the most fiat script and force the largest number of others to accept it....wins".
