Dangerous game to play, in my opinion. If the Iranians explode a nuke or throw a missile at Israel, the whole world will jump back on $ and you are toast. Or if Al Queda gets control of nukes in Pakistan (there is only a weak dictator standing between them now), the markets will just discard other currencies in favor of $. Currency speculation is for grown ups. You should understand the global dynamics far too well to play and win.
